I do recall this whas brought up before; I don't recall whether a good
reason was given to kill it apart from that it doesn't add a whole lot
of joy either. There are probably lots of niggling decisions to be
made about whether int("1_000") should work, and a formatting code
that inserts _ every three characters, and whether to accept
abominations like 12__ or 0_x_ff or 3.14_e_1_0_0.
But if someone cares enough to write a PEP that covers all the corner
cases with reasonable rules *and* a complete implementation, it would
be a lot harder to say no.
(See my PS on code vs. PEPs in a previous post in a different thread
on this list.)
