Is it a premature micro-optimization which is unlikely to have anything but a negligible impact the vast majority of real world code? Yes.

No, its called style :)

map, grep, sort, s{}{...}e don't allow you to use return, they force you to use implicit return

explicit return isn't required in do/eval/sub

return tells you about this

so unless you're coding something recursive, something that requires short circuiting, most perlish perl programmers omit the explicit return, and use the implicit return

If explicit return costs more (I'll take BrowserUk's word that it does), its a problem with the implementation, something for p5p to fix, same as they did for map in void context
