There's more important reasons why everyone should always call functions
with parenthesys: If you use just &func; then caller's @_ get's passed
to func which isn't usually what you meant. That's why you should always
use &func (); form. Here's a little example which prints out "Hello
World!":

sub func1
{
	foreach (@_) { print $_ }
}

sub func 2
{
	&func1;
}

&func2 ("Hello World!");
