Yeah, maybe this is worth it for the simplicity.

Should the latter be !DISABLE_EXCEPTION_THROWING? We allow throwing exceptions even when DISABLE_EXCEPTION_CATCHING is true. We should be throwing CppException and not a number in that case too, no?

No, I believe that then catching is disabled we just abort instead of throwing so there should be nothing to actually throw.

Yeah, forgot that we call abort in that case. LGTM

I could split this PR up into smaller ones if you prefer? |
This has a slight codesize cost but it means we no longer have to worry about the ambiguity in when we catch a Number.
