> do I need them every time I declare a variable? Nope. The parens force "list context". Without them is "scalar" context.
For example... my @foo = qw(1 2 3 4 5); my $x = @foo; # =5, the number of elements my ($y) = @foo; # =1, the first element Certain functions and operations will do different things based on the context they are called in. For example when setting a scalar to an array (like above), the number of elements is returned... but when setting an array to a list (like above) you get as many elements as you have variables. Hope that helps.
