desugar :: (MonadSupply m, MonadError MultipleErrors m, MonadWriter MultipleErrors m, MonadState (Env, UsedImports) m) => [ExternsFile] -> Module -> m Module #

The desugaring pipeline proceeds as follows:

- Remove signed literals in favour of `negate` applications
- Desugar object literals with wildcards into lambdas
- Desugar operator sections
- Desugar do-notation
- Desugar ado-notation
- Desugar top-level case declarations into explicit case expressions
- Desugar type declarations into value declarations with explicit type annotations
- Qualify any unqualified names and types
- Rebracket user-defined binary operators
- Introduce newtypes for type class dictionaries and value declarations for instances
- Group mutually recursive value and data declarations into binding groups.
