No, it's not about codifying.  It's about having a *significantly
better* solution by modifying the language than working within the
language.  List comprehensions are significantly better than a full
for-loop.  Adding a keyword is not significantly better than returning
your next function; it's actually worse.

It's a non-solution to a non-problem.  If you actually *had* a problem
you could do it with trampolines.  They do exactly what's needed, they
just don't put a bow on it.  Ho hum.
