Re: Modify array elements inside for loops

my @new_a = map { $_+1 } @a;

(faster? maybe not, but cooler and shorter, yes =)

Whether or not this is what you want depends on what you are planning to do with the modified values. You could always do:

foreach ( map { $_ +1 } @a ) {
 #whatever
}

Hmm. After experimenting (albeit with 5.5.3, the most recent usable release), I have seen that: `foreach (map $_, @a) { $_++; # then whatever }` [download] is sufficient. Cool, I'll add that to my trick bag. Much easier than that crazy nested `@{[@a]}` I've seen so often (and think I actually invented from first principles at one point). -- Randal L.
