As Fredrik suggested, we bought front ends whenever possible. When a single
machine sells for millions, and you can buy a highly regarded front end for
a few percent of that, you'd be crazy to write your own.

I'd be more upset if anyone had proved that C++ is compilable <wink>.

As Fred and Jeremy said, when we (PythonLabs) worked intensely on closing
bugs for 1.6 and 2.0, we were close to being in phenomenal shape here. We
don't have a fraction of the internal resource to throw at that anymore,
though, and volunteers haven't taken up the slack. So I figure the only
reason Python stays in exceptionally good bug shape is that we also ignore
the contributed patches <0.9 wink>.
