{- COMPLETION SORTING
   We return an ordered set of completions (local -> nonlocal -> global).
   Ordering is important because local/nonlocal are import aware, whereas
   global are not and will always insert import statements, potentially redundant.

   Moreover, the order prioritizes qualifiers, for instance, given:

   import qualified MyModule
   foo = MyModule.<complete>

   The identifiers defined in MyModule will be listed first, followed by other
   identifiers in importable modules.

   According to the LSP specification, if no sortText is provided, the label is used
   to sort alphabetically. Alphabetical ordering is almost never what we want,
   so we force the LSP client to respect our ordering by using a numbered sequence.
