I assumes lexical refs and dynamic refs are not different, as they are just a means of finding the data and freeing it's space when unused.... What I ment by reference is actually not the referencing part of it, more the resolving to a value. I should have not used the word reference, as it is not correct...
In terms of my question - I guess i need to be more clear - How are lexical variables found via their name, and does the symbol table -> value path work like I assumes?
