Yes, Ruby. But there's tradeoffs and frankly Python's file name = namespace name approach makes finding things much easier when you don't know where they've been imported from.

In Ruby people achieve something similar by convention (explicitly creating a namespace and keeping the names in sync with the file name), but not everyone follows convention and things can turn into a mess.

If I had to suggest one flaw in Ruby it would be this, in many other ways I find it nicer to code in then Python, but honestly this one thing is enough to really sour the experience.
