The last expression evaluated in a subroutine is returned, but you can
explicitly return a value by doing:
return $some_value;
If you have multiple values to return, put the return values into a list
context and grab it back that way:
sub some_sub {
#do stuff
return @vals;
}
my (val1, val2) = some_sub;
This is also a good way to return errors, failure of an algorithm (by
returning a false value, etc:
if(!some_sub()) {
# do something
}
