New submission from catrudis <ar12...@gmail.com>:
ELSE-clause in FOR and WHILE has unclear syntax. I suggest new clause instead:
if COND:
...
[elif 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.
COND may be "break", "pass" or "finally". "if break:" - if used break-operator
to exit cycle. "if pass:" - cycle executed 0 times. "if finally:" - cycle
executed 0 or more times ("pass-case" is included in "finally-case"). For
compatibility only "else:" means "if finally:".
It's compatible enhancement. No new keyword. There can be no combination
"break", "pass" or "finally" after "if"/"elif:" in current version.
