Yeah, my mental model got the better of me there. I conceptualize try/except as deferring subsequent reraises in the try block, so in that case the "catch all --> do nothing ( --> defer reraise)" and "catch nothing (--> defer reraise)" cases were equivalent. But the way I wrote it was confusing because it sounds like I was implying it just passed, especially because catching the exception requires a manual reraise and the implicit case does not. Hopefully that makes sense?
And yes, I think I was narrowing the case that was originally presented to just allowing an omitted except following the behavior you said. Either way, sorry, to drag this out. I'm not particularly concerned about the current setup because, like you said, just adding an except/raise isn't hard and only two lines. Also, I do actually put more weight on the linguistic semantics than my previous messages suggested: try/else linguistically strikes me as meaning more-or-less the same as try/except—the else provides the opposite condition with respect to what's excepted, not what's being tried. And I certainly do *not* advocate for adding or renaming a keyword.
