Documenting this syntax with the appropriate warnings and clear
explanations is very important.

But I don't think the amount of code mishaps on this thread are
properly addressed just by better documentation. The syntax I proposed
is harmless, it won't break any existing code, and it's something
people in python 3 can use right now. Deprecation etc can wait for
python 4. Don't tea5e me :)

Of course people here would have to say if my idea sounds good or not.

while still_more_items():
    if found_it():
        break
if not break:
    # exhausted search space
