Okay. I see what you're saying about the parameters now. I was thinking of doing something like this:
my %meminfo = { TotalPhys=>0, AvailPhys=>0 }; MemoryStatus(\%meminfo,"KB");

but it seemed like too much work to make the user do, and setting hash values to 0 might be confusing. It would lessen the task of checking the parameter list, though, and we still have a hash reference which I agree is better than returning a specifically ordered list. Maybe I can include both options?

    Silly trick:
    my %args = %default, @_; foreach my $arg (keys %args) { unless (exists $allowed{$arg}) { croak("Unrecognized argument '$arg' passed to MemoryStatus."); } }
    Just put all possible defaults in %default and the user can override any combination they want, and your %allowed check will catch most typos and misunderstandings of the API.
