Please don't forget to make sure that you are in the correct compiler phase which can guarantee that required declaration parts are resolved. For example, it's illegal to access resolved return type of some function in `STATUS` stage, because at this point of time implicit return types are not
resolved. Implicit types are resolved at `IMPLICIT_TYPES_BODY_RESOLVE` phase.
