Re your last solution: what do you gain by localizing $_? Or, equivalently, what is the difference between 

@my_array_2 = map { local $_ = $_; s/^CHOP_ME_OFF_//; $_ } @my_array;

and 

@my_array_2 = map {s/^CHOP_ME_OFF_//; $_ } @my_array;

I've used the latter version often and it seemed to work perfectly fine...

Update:OK, to be honest what I really used was 

@my_array = map {s/^CHOP_ME_OFF_//; $_ } @my_array;

i. e. I did the replacements in-place, which explains why I never noticed the effect pointed out by adrianh++.
