  -- | The method 'displayList' is provided to allow for a specialised
  -- way to render lists of a certain value.
  -- This is used to render the list of 'Char' as a string of characters
  -- enclosed in double quotes, rather than between square brackets and
  -- separated by commas.
  --
  -- === Example
  --
  -- > import qualified Data.Text.Lazy.Builder as TB
  -- >
  -- > instance Display Char where
  -- >   displayBuilder c = TB.fromText $ T.singleton c
  -- >   displayList cs = TB.fromText $ T.pack cs
  -- >
  -- > instance Display a => Display [a] where
  -- >   -- In this instance, 'displayBuilder' is defined in terms of 'displayList', which for most types
  -- >   -- is defined as the default written in the class declaration.
  -- >   -- But when a ~ Char, there is an explicit implementation that is selected instead, which
  -- >   -- provides the rendering of the character string between double quotes.
  -- >   displayBuilder = displayList
  --
  -- ==== How implementations are selected
  --
  -- > displayBuilder ([1,2,3] :: [Int])
  -- > → displayBuilder @[Int] = displayBuilderList @Int
  -- > → Default `displayList`
  -- >
  -- > displayBuilder ("abc" :: [Char])
  -- > → displayBuilder @[Char] = displayBuilderList @Char
  -- > → Custom `displayList`

  -- | The method 'displayPrec' allows you to write instances that
  -- require nesting. The precedence parameter can be thought of as a
  -- suggestion coming from the surrounding context for how tightly to bind. If the precedence
  -- parameter is higher than the precedence of the operator (or constructor, function, etc.)
  -- being displayed, then that suggests that the output will need to be surrounded in parentheses
  -- in order to bind tightly enough (see 'displayParen').
  --
  -- For example, if an operator constructor is being displayed, then the precedence requirement
  -- for its arguments will be the precedence of the operator. Meaning, if the argument
  -- binds looser than the surrounding operator, then it will require parentheses.
  --
  -- Note that function/constructor application has an effective precedence of 10.
  --
  -- === Examples
  --
  -- > instance Display a => Display (Maybe a) where
  -- >   -- In this instance, we define 'displayPrec' rather than 'displayBuilder' as we need to decide
  -- >   -- whether or not to surround ourselves in parentheses based on the surrounding context.
  -- >   -- If the precedence parameter is higher than 10 (the precedence of constructor application)
  -- >   -- then we indeed need to surround ourselves in parentheses to avoid malformed outputs
  -- >   -- such as @Just Just 5@.
  -- >   -- We then set the precedence parameter of the inner 'displayPrec' to 11, as even
  -- >   -- constructor application is not strong enough to avoid parentheses.
  -- >   displayPrec _ Nothing = "Nothing"
  -- >   displayPrec prec (Just a) = displayParen (prec > 10) $ "Just " <> displayPrec 11 a
  --
  -- > data Pair a b = a :*: b
  -- > infix 5 :*: -- arbitrary choice of precedence
  -- > instance (Display a, Display b) => Display (Pair a b) where
  -- >   displayPrec prec (a :*: b) = displayParen (prec > 5) $ displayPrec 6 a <> " :*: " <> displayPrec 6 b

-- $designChoices
--
-- === A “Lawless Typeclass”
--
-- The 'Display' typeclass does not contain any law. This is a controversial choice for some people,
-- but the truth is that there are not any laws to ask of the consumer that are not already enforced
-- by the type system and the internals of the 'Data.Text.Internal.Text' type.
--
-- === "🚫 You should not try to display functions!"
--
-- Sometimes, when using the library, you may encounter this message:
--
-- > • 🚫 You should not try to display functions!
-- >   💡 Write a 'newtype' wrapper that represents your domain more accurately.
-- >      If you are not consciously trying to use `display` on a function,
-- >      make sure that you are not missing an argument somewhere.
--
-- The 'display' library does not allow the definition and usage of 'Display' on
-- bare function types (@(a -> b)@).
-- Experience and time have shown that due to partial application being baked in the language,
-- many users encounter a partial application-related error message when a simple missing
-- argument to a function is the root cause.
--
-- There may be legitimate uses of a 'Display' instance on a function type.
-- But these usages are extremely dependent on their domain of application.
-- That is why it is best to wrap them in a newtype that can better
-- express and enforce the domain.
--
-- === "🚫 You should not try to display ByteStrings!"
--
-- An arbitrary ByteStrings cannot be safely converted to text without prior knowledge of its encoding.
--
-- As such, in order to avoid dangerously blind conversions, it is recommended to use a specialised
-- function such as 'Data.Text.Encoding.decodeUtf8'' or 'Data.Text.Encoding.decodeUtf8With' if you wish to turn a UTF8-encoded ByteString
-- to Text.
