Because the parser needs to know about it (to support Numeric).  Indeed,
it's not a syntax error that you're getting.

I think it was introduced in 1.5.2.

No idea.  The original intro was before PEPs, so there's not even a
PEP to refer to, I believe.  You may want to ask on Python-Dev --
if the BDFL OK's it for 2.3, I can write the code, if you or some other
volunteer can handle the rest of the patch submissal process (sorry,
can't volunteer more time than what it takes to write & debug the code).
