Really? Is WASM JIT-optimized?

I mean if a Perl Op-Code deals with Scalars will it automatically be optimized to integer if some tracker finds that all calls to the surrounding function always result to paths using Int?

That would surprise me...

Don't you think that for little UI callbacks handling some AJAX compiling the whole Perl core to 4 MB WASM is kind of overkill?

Gimme some example Perl code for a start and I'll try to "B::Deparse" it into working JS.

Actually I'm wondering why this is not generally used for JITing Perl. (Probably some weird side effects or performance brakes of calling subs.)
