actually I don't wanna get rid of the feature but of the syntax.

better something like strinc() which does the same.

(EDIT: Out of millions of postincs only few are supposed to increment strings, no need to share the operator.)

I'm using this productively¹, but again I'd rather prefer another syntax, something like m/$¬LAST/ for matching the last successful regex.

we had a keynote talk about this in Riga ...

... but I asked about the chances that this really happens soon.

These side-effects make translating Perl5 to other languages a pain in the *ss.

perlito for instance gets it "wrong".

If you think about the steps needed to mimic this behaviour in JS ... maybe with something like a function

postinc(variable)

which handles the cases it gets incredible complicated and slow for such a basic operation like ++, especially because JS can't do call-by-references.
