Yet, this *still* is a platform dependence. Python makes no guarantee
that 1e1000 is a supported float literal on any platform, and indeed,
on your platform, 1e1000 is not supported on your platform.

Furthermore, Python makes no guarantee that it will report when an
unsupported float-literal is found, so you just get different behaviour,
by accident.

This, in turn, is a violation of the principle "errors should never
pass silently". Alas, nobody found the time to detect the error, yet.

Just don't do that, then.
