sucking the hash into ref would safe some speed and memory (because it has not to be copied). You're other point is correct. A simple way to make it "smarter" is 

sub foo
{
  my %defaults = 
  {
    param1 = 'default1',
    param2 = 'default2',
    #etc
  }

  my $self = shift;
  my $params = { @_ };

  for ( keys %defaults )
  {
    $params->{$_} = $defaults{$_} unless defined $params->{$_};
  }
}

Also there are parameter checking modules out there.
I can't remember the names but i'm sure someone will mention them.
