Dear Perl Monks:

1. How to write a function which can accept either a scalar or a hashref as a parameter.
2. How to find out whether the received parameter is a scalar or a hashref 
my $code = 'default';
my $hash = {"1"->'ENABLE', "2"->'DISABLE'};

# Call function foo with the scalar
my $ret = foo($code);

# Call function foo with the hash
$ret = foo($hash);

sub foo(){
  $param = shift;

  # If $param is a scalar
    # Do something
  # Else
    # Do something
}
