Re^2: getting rid of special featuresby LanX (Chancellor)

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
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.
