Regardless of the relative merits of tabs vs spaces, tabs make the most sense _specifically in a Python-like language_.

I don't care about tabs vs spaces, I just don't want to have the "inconsistent identation" problem, and spaces are more fundamental (you can convert arbitrary tabs to spaces, you can't convert arbitrary spaces to tabs).

Also you cannot forbid spaces in code, but you can easily forbid tabs.
