what are those members of the block? compound statements, or what? (what
derived classes of Symbol)

how do I know for 100% what class was this Block originally? do I have to go
back to the AST from the block (some way, not sure if I know this
precisely?)

or the current state of code is, that you only make a Block from the body of
a method, without taking care of real body?

what do you mean by this new pass?

Thanks a lot
