rnSourceDecl
"renames" declarations.
It simultaneously performs dependency analysis and precedence parsing.
It also does the following error checks:
- Checks that tyvars are used properly. This includes checking
for undefined tyvars, and tyvars in contexts that are ambiguous.
(Some of this checking has now been moved to module
TcMonoType
, since we don't have functional dependency information at this point.) - Checks that all variable occurrences are defined.
- Checks the
(..)
etc constraints in the export list.
Brings the binders of the group into scope in the appropriate places; does NOT assume that anything is in scope already
