ELSE-clause in FOR and WHILE has unclear syntax. I suggest new clause instead:
if COND:

[else:

This IF-clause like must be immediately after FOR- or WHILE-cycle (only
comment allowed between). It looks like a regular IF, but COND is
special.

Something to consider: Would it be legal to mix these CONDs with other
conditions in the 'elif' chain? E.g.
if break:

elif x > 0:

elif finally:
What if "instead of a special kind of if clause that can only be placed after a
loop", we simply defined these three special expressions [usable in any if/elif
statement] to reference special boolean flags that are set after exiting any loop?
The problem is: how long would these "special boolean flags" be retained?
Could they still be tested
100 lines of code later (assuming no other loops were executed)?
After returning from a function?
Inside a new function call?
etc.
This would violate the principle of ... I can't remember the computer
science name for it, but let's call it ... local transparency.
