in reply to Re^2: unexpected modify hash in a distance with grep { $_ }
in thread unexpected modify hash in a distance with grep { $_ }

Found another related discussion, curiously from the same OP.

No autovivification, for loop aliasing, lvalue vs rvalue in for loops

The related bug report argues, that aliases must trigger autovivification beforehand, in case an lvalue happens after.

https://github.com/Perl/perl5/issues/15583

I find this explanation unsatisfactory because I showed here that the aliasing of sub arguments don't trigger autovivification.

Hmm???
