But even if it is, that might be a consideration for a new language, but
adding it to python now is pretty darn unlikely.

now I"m confused -- if it's not a great sytle, why suggest it?
and I was thinking that the one good thing is that the "return" or "break"
is a bit more prominent -- which could be a good thing.
Alternatively, is there a good way I can implement this as a

I'm pretty sure not -- python is very dynamic, but not let you redefine the
Other than as a import hook that re-wrote the code on the fly.
but really -- don't do that -- then no one else will understand your code.
