Actually, I don't mind of __builtins__, but of vars() or locals(). The issue is that __builtins__ were monstruously ;-) obfuscating a scope dict I needed. In fact, I printed it out to check it contains what I want; when I saw all that stuff there I thought there was something wrong in my method. Actually the dict contains what I need, and only 4 elements. Simply one of them is veeery BIG.

For the sake of information, the reason for this is I need a kind of dynamic scoping, i.e. getting the vars from the caller scope; while python is statically scoped. I cannot find any other way than passing e.g. vars(). Hints welcome.

By the way, I asked previously about the difference between vars() and locals() (couldn't find a situation where they differ). Still have no idea, and there seems to be nothing about that in docs. So why both?
