Sorry - personally I think this is absolutely ugly :-) So I will bikeshed.
If this thread even go ahead - since the idea is not that bad, maybe allowing `try` on the same line? Then it would be inline with `elif` - but still structured "English like" try: statement except ValueError try: statement2 except TypeError: ... I had sometimes needed 2 and maybe up to 3 levels of this, nothing 'blocker', but maybe, just maybe, it would not be bad. However, in real life, usually one wants to put more statements on the `except` clause than a bare nested try block. (logging, etc...)
