Description

Check for label uniqueness should be added.

Check should work on the scope level, i.e. we can have multiple same labels within the one script, but they cannot belong to the same scope.

Shouldn’t be too complicated, each visit method has a corresponding enter/exit method for each node that can be overridden as well and thus we can easily handle scopes.
