Is there a better way than this to deference a hashref arg? I mean, maybe a way in one line? Also, it would be nice if there were some way to die if the arg was not a hashref. 
    my $arg = shift or die "no arg";    
    my %arg = %{$arg};

UPDATE: Thanks for pointing out the obvious, LR et al. There's really no reason to do this; I'm rewriting my code with just the ref.
