My question is, why not move them into, say, a "functional" library,
so that legacy code can be handled via an import, and those heads
preferring to think that way can be satisfied, and those little corner
cases not handled by the newer, sweller syntaxes can still be managed?
IOW, just ripping them out of the core and leaving everyone in the
lurch doesn't seem too pythonic to me.
Best,
