In my experience it's better to discover a bug at compile time rather than at running time. That's my point though, which you seem to be ignoring: if the user explicitly writes "1/0" it is not likely to be a bug. That's very different than "1/x" where x happens to take on zero at runtime -- *that* is likely bug, but a constant folder can't detect that (at least not for Python).

I agree. My only concern was about user mistyping that can leed to an error interceptable by a stricter constant folder.
But I admit that it's a rarer case compared to an explicit exception raising such the one you showed.
I would guess that it is so rare as to not be worth bothering about.
