This module re-exports the functionality in 'Data.Vector.Generic.Sized'
 specialized to 'Data.Vector.Unboxed'.

Functions returning a vector determine the size from the type context unless
they have a @'@ suffix in which case they take an explicit 'Proxy' argument.

Functions where the resulting vector size is not known until runtime are
not exported.

-- | Pattern synonym that lets you treat an unsized vector as if it
-- "contained" a sized vector.  If you pattern match on an unsized vector,
-- its contents will be the /sized/ vector counterpart.

-- @
-- testFunc :: Unsized.Vector Int -> Int
-- testFunc ('SomeSized' v) =
--     'sum' ('zipWith' (+) v ('replicate' 1))
--         -- ^ here, v is `Sized.Vector n Int`, and we have
--                     `'KnownNat' n`
-- @
--
-- The @n@ type variable will be properly instantiated to whatever the
-- length of the vector is, and you will also have a @'KnownNat' n@
-- instance available.  You can get @n@ in scope by turning on
-- ScopedTypeVariables and matching on @'SomeSized' (v :: Sized.Vector
-- n Int)@.
--
-- Without this, you would otherwise have to use 'withSized' to do the same
-- thing:
--
-- @
-- testFunc :: Unsized.Vector Int -> Int
-- testFunc u = 'withSized' u $ \\v ->
--     'sum' ('zipWith' (+) v ('replicate' 1))
-- @
--
-- Remember that the type of final result of your function (the @Int@,
-- here) must /not/ depend on @n@.  However, the types of the intermediate
-- values are allowed to depend on @n@.
--
-- This is /especially/ useful in do blocks, where you can pattern match on
-- the unsized results of actions, to use the sized vector in the rest of
-- the do block.  You also get a @'KnownNat' n@ constraint for the
-- remainder of the do block.
--
-- @
-- -- If you had:
-- getAVector :: IO (Unsized.Vector Int)
--
-- main :: IO ()
-- main = do
--     SomeSized v <- getAVector -- v is `Sized.Vector n Int`
--     -- get n in scope
--     SomeSized (v :: Sized.Vector n Int) <- getAVector
--     print v
-- @
--
-- Remember that the final type of the result of the do block ('()', here)
-- must not depend on @n@.  However, the

--
-- This enables interactive exploration with sized vectors in ghci, and is
-- useful for using with other libraries and functions that expect sized
-- vectors in an interactive setting.
--
-- (Note that as of GHC 8.6, you cannot get the @n@ in scope in your ghci
-- session using ScopedTypeVariables, like you can with do blocks)
--
-- You can also use this as a constructor, to take a sized vector and
-- "hide" the size, to produce an unsized vector:
