Well, I don't think you need to generate code like


EnterScope(my_func);


In my understanding, the meaning of scope is to help the code
generator to generate code, after code generation phase, I don't think
it would be necessary to keep the scope in the memory. You could go
and discard the scope.


And go on with the further optimization work.
