in reply to Shortcut operator for $a->{'b'}=$b if $b;

You could abstract $b away into a sub (I'm assuming you're using it as a placeholder for a complex operation), and do something like:

sub b { return $b; } b() and $a->{'b'} = b();

I guess I don't really understand where your "way too verbose" is coming from; it would help if I could see a more involved example of the code you're attempting to simplify.

[james28909]: two or three. if it has to do with how humans are handling said situations, then that is after they were able to evolve into those problems. agnostic means only believe with evidence. i took that from a tyson video
[james28909]: and it seems that racism suggest that there is indeed a better race, but that is for evolution to decide
[1nickt]: "right now, humans are smarter than in any of those times": define "smart"
