I emphasised one point of your comment however. When i see a map in void context that isnt part of an obfu or some CB whip-it-together, my first thought is "Hmm, what happend to the target of the map?" And then I go looking to see what I dont understand. And then I get annoyed and change it to a for loop so that nobody else wastes time trying to figure out the misleading code.
And that is something I don't understand. What makes map so
special? Any function in Perl will return
something, be it a buildin or a user defined sub, and even
operators return values. Why is it that people get all confused if they see a map in void context, and start looking where the return value goes, but they don't have
problems with other functions?
What makes map so special?
