I don't think that. I was just illustrating that using:
"That is unpythonic" isn't really an argument, because
things that were thought unpythonic before are now
accepted as the pythonic way.

There were people who annouced these features in this newsgroup
for version 2.5 with a rather clear titles and those from the
dev-list that frequent this newsgroup didn't protest.

Among the PEP's I see that at least PEP 308 is accepted.
So although it may not be implemented for version 2.5
a ternary operator is now an accepted as being pythonic.
