Not sure if I was able to help you, this area of implementation details is a moving target.

And the margins you benchmarked do not really justify any micro-optimisations here, because different Perl versions can behave differently.

Personally I'd rather prefer for to alter an array via alias, such side-effects in map might confuse other readers (a map in void context used to be a matter of warning)
