Re: Passing hashes as arguments to a sub?

I'm not familiar with Params::Validate that was mentioned; however, there is a simple example of being strict with hash keys in "Perl Medic." It goes something like this:

sub name {
  # this puts the passed list into a hash
  my %arg = @_;
  # this transfers values to variables and removes the keys
  my ($key1, $key2) = delete @arg{qw(key1 key2)};
  # this determines if any keys are leftover
  croak 'Illegal arguments' if %arg;
}
