Yeah, that's probably why most popular scripting languages support it.
In Ruby:
def foo
1, 2
end
a, b = foo
In Python:
def foo
return 1, 2
a, b = foo
In Perl:
sub foo
{
return (1, 2);
}
(my $a, my $b) = foo;
For completeness sake, this is pretty much the same in PHP:
function test() {
return array(1,2);
}
list($a,$b) = test();
works as above. Works fine with complex arrays as well:
function test() {
return array(1,array('a','b'));
}
list($a,$b) = test();
