Can I suggest that for loops the `else` would be a lot clearer if it was spelt
`finally` as was done for PEP-0341 for try blocks and that we might possibly
need one or more `on_…` clauses such as `on_break` and `on_finish` I think that
this would be a lot clearer:
for i in range(N):
if i > 3:
break;
on_break: # Called if loop was broken
print(i)
on_finish: # Called if loop was not broken
print("Loop Completed")
finally: # Always called (replaces for…else)
print("Loop Ended")
Which I think would be a lot easier for newcomers to learn than
try…for…else…except…else e.g.:
try:
for i in range(N):
if i > 3:
break;
elif i % 2 == 0:
raise ValueError("Odds Only");
else: # to if
print(i)
else: # Else to loop
print("Loop Completed")
except ValueError as err:
print(err)
else: # to try
print("No Exception")
finally:
print("Try Ended")
Where the multitude of elses makes my eyes cross.
