Indeed. Because they are needed. Because they add functionality that Python
doesn't already have, or seriously improves the interface to that
functionality.

"Preferably using a new keyword"?
Dear gods, you really have *no clue* about the responsibilities of
maintaining a programming language used by tens of thousands of people.
Adding your new keyword will break thousands of peoples programs. That's not
to be done lightly, on a whim, just because you don't like the spelling
`while True`.

Right. We don't need to test this new feature, because we have such awesome
mad skillz that of course it will work perfectly first time.
Nor do we need to document this new feature. We don't need to include it in
the "What's New" documentation, or include it in the tutorial, or mention
it in the list of keywords, or in the description of the grammar.
Documentation is for people who don't already know the source code because
they wrote it.
People will work it out for themselves. Eventually. After many hours, or
days, of pulling their hair out at why their working code has suddenly
stopped working after upgrading to a new Python version.
The only thing you could do that would be more irresponsible would be to
insist on introducing this new, undocumented, untested, unnecessary feature
in a bug-fix point release.
Ah, but I'm guessing that you don't understand the need for point releases
either? With only one user, yourself, who needs releases or version
numbers?

Damn straight. Now you get it. It's not about how easy it is to implement,
it's about whether it is needed and wanted. It isn't needed, and it isn't
wanted.

Well, the thing is, there are two kinds of no-brainers. There are the kind
of things that are so obviously a good idea that it requires no brain to
want it.
And then there are the kinds of things that are so obviously a bad idea that
it requires no brain to want it.
Which is this, do you think?
