- Identifiers with just a semi-colon in front now have "lux" as their module, instead of the local module. (e.g. ;map, #;Cons, ;All)
- The type-checker now takes into account 2 types: an exo-type (imposed by outside forces) and an endo-type (generated through inference)
- Fixed a few bugs in the analyser and the type-system.
- &type/solve* is now the actual type-checker and &type/solve invokes solve* with an empty fixpoint environment.
- The exo-type of Statements is Nothing.
- variants, tuples and def' are being analyzed properly now.
