The "significant whitespace problem" is one of the drawbacks of Python, IMO. I thought we deprecated that way back in make? That is, why would someone choose to do that, after having suffered through using make?

In Python, I also miss having an enclosing block entity, to limit the scope of variables.

And it seems it's too easy to accidentally create a tuple by grouping things in parens, which then returns the wrong type to something not expect an iterable. ARG!
