I agree with you on "then" giving no clues but I think you're wrong
about the spelling. The correct spelling would be "if not break".
x = y / z
The above code translated to "George Sakkis Language" should be spelled:
x = y / x
if condition and notreturnandnotexception:
So because it's obvious that everything in python is under the
condition of "notreturnandnotexception", your point is moot.
The "else" in "for...break...else" is very simply a condition tested
after the loop finished (exactly like any other "if" that would
immediately follow the loop). The condition that's tested is simple:
"if there was a break - skip this".
So your spelling exaggeration doesn't worry me :). The fact that
python-ideas can't agree on a better syntax for python 4/5 does. I
appreciate the lesson taught, as Guido put it, but I think python can
have a long term plan concerning this old, rare and misleading syntax.
