Oh, the syntax of foreach has those parentheses
foreach my $iterator (things to iterate over) {
}
Where the things to iterate over can be a simple list of values, an array or
anything that returns a list of values which of course can be any expression.
foreach my $iterator (1,2,3,4,5) {
}
or for the lazy ones
foreach my $iterator (1..5) {
}
or for the really lazy ones:
for my $iterator (1..5) {
}
or
foreach my $iterator (@names) {
}
foreach my $iterator (@$ref) {
}
foreach my $iterator (function_that_returns_thingies()) {
}
