To be fair, that can be an important distinction. I don't like seeing
code like this:
def f():
x = g()
y = h(x)
return 5 + x
What's y for? Why not just call h(x) and ignore its return value?
Should the last line say "5 + y"? It looks _wrong_ to have a local
variable that's never used. It's still not a consideration strong
enough to demand new loop syntax, though.
