Hello,

For now Opal is not using the semantic analysis of AST-Semantics but instead it's own.
(it is more low-level with escaping variables and things like that).

So the goal is to merge the two.

What I wanted to say: No idea. :-)

In Opal, self, super, thiscontex is in the Method Scope while self and super is in the
Instance scope.

So the lookup is

temps + thisContext
ivars + self + super
literal vars
