This pull requests checks for the well-formedness of types, and allows to infer the kind of any algebraic data type. Additional support for GADTs should be possible from what's already implemented. I also prepared the possibility for the user to define type aliases (for now there is just an
undefined
for them, since there is no parser for type aliases this should not be a problem). Types can be used in a function type signature before they are defined, since the type declarations are analyzed beforehand. However, mutually recursive type declarations are yet to be handled. The REPL now features a GHCi-inspired:kind
command to see the inferred kind of any type.
