Python with braces.

[Alex]

I don't think there's an interpreter that can handle Python with braces,
but there is a preprocessor that can take Python with control structures
delimited by braces, and format it with the appropriate indentation for
the vanilla Python interpreter.  I've never tried it, because it seems
like a terrible way to code, for me, even though it's a cool idea.  But
you can find it here:
