I'll make it a little simpler. If A is the type of aggregate (Array, Hash, RowOfKennels) and E is the type of element (Scalar, String, Dog), here's where each goes: my E @var; #assumes Array my @var of E; #same my E @var is A; #No assumption my @var is A of E; #same 'returns' is an exact synonym of 'of', so for the same of clarity and brevity I'll ignore it. (I would suggest, though, that anyone who uses 'returns' here in real code should be shot.) Notice that E is always either at the front or behind an 'of', and A is always after an 'is'. (If you think of a variable as a stack of properties, this 'is' is just specifying the root property.) Is that clear enough, or should I say it a little slower? --Brent Dax <[EMAIL PROTECTED]> @roles=map {"Parrot $_"} qw(embedding regexen Configure) "If you want to propagate an outrageously evil idea, your conclusion must be brazenly clear, but your proof unintelligible." --Ayn Rand, explaining how today's philosophies came to be
