[$] "Real" anonymous functions for Python

There are a number of different language-enhancement ideas that crop up
with some
regularity in
the Python community; many of them have been debated and shot down multiple
times over the years. When one inevitably arises anew, it can sometimes be
difficult to tamp it down, even if it is unlikely that the idea will go
any further than the last N times it cropped up. A recent discussion about
'real' anonymous functions follows a somewhat predictable path, but there
are still reasons to participate in vetting these 'new' ideas, despite the
tiresome, repetitive
nature of the exercise—examples of
recurring feature ideas that were eventually adopted definitely exist.
