Yes, always pass an array as a reference when passing multiple arguments to a subroutine.

You de-reference the array in the sub like so: 

my ($var,$rlist) = @_;

# de-reference $rlist like so: @{$rlist} - but, TIMTOWTDI ;)

foreach(@{$rlist}) {
    #do stuff
}

UPDATE:
Almost forgot about this one: 
my $var = shift;
my @list = @{+shift};  
# you cannot use @{shift}, the + operator tricks perl
# into getting the value of shift first
