Also the resolver needed some extra logic with regards to the init `self` argument, though not entirely sure if needed (specifically the `resolve_reference_expression` needs to match on a `ReferenceExpr`?) Finally there still seems to be some issues regarding the const evaluator, since one validation ("Some initial values were not generated") reported an error.
