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()) {
}
