I don't think special syntax is warranted for this. You can write:
try:
first = next(iterator)
except abdl.exceptions.ValidationError as e:
validation_handler(e)
except StopIteration as e:
return stop_handler(e)
I agree - and this is far more readable than any
of the propositions so far. (Like, for an order of magnitude).
I'd wait for Soni to try to explain why this would not
fit his use case, before proceeding with the
bikeshedding.
have you looked at the syntax highlighting of the thing?
it sees keywords *everywhere* (which is right) it's basically
unmaintainable. having the exception handlers have an exceptional syntax
would set them apart from the rest of the code and make the whole thing
much easier to read and maintain.
it's hard to reason about it if your eyes just keep jumping into the
except bodies because they have the same indentation and everything as
the normal code. I am gonna say my proposal improves accessibility, even
if it doesn't make a difference to most ppl.
