Fixes complex datatype's symbol duplication bug while using interactive

Orginal Bug:

❯ lp
>>> l: list[i32] = [1, 2, 3]
>>> print(l)
Internal Compiler Error: Unhandled exception
Traceback (most recent call last):

I just followed the way visit_Variable handles normal integer types and adapted it to work with list, dict, etc.
