Is there something like `last` for `map`?

Question

In Perl, is it possible to arbitrarily end a map execution, e.g. something equivalent to last in a loop?

It would be a bit like this:

map {
    if (test == true) { last; } dosomething
} @myarray

Answer 1

Nope. You can't last, next, etc. out of a map, grep or sort blocks because they are not loops.

Having said that, the code snippet in the question is poor practice because map should never be called in void context. They are supposed to be used to transform one list into another.

Here's a better way to write it if you really must inline it (modified after ysth's comment):

 $_ == 10 && last, print for 1..15;  # prints '123456789'
