I am wondering if there exists a faster way?

What do you mean faster? Faster to write? Faster to run? Faster to read and understand? What are you trying to optimize for, or is this just a thought exercise?

I'd generally suggest using any of a number of class generating tools -- these usually have syntax which are fairly self documenting. Personally, I don't find that protected functions are really common in Perl unless you're an OO purist.

However, protected fields are already supported by Object::InsideOut, and in five statements of code:

package My::Class;
use Object::InsideOut;

my @FLYBEHAVIOUR :Field( 'Accessor' => 'FLYBEHAVIOR', 'Restricted' => 
+1 );

my @QUACKBEHAVIOUR :Field( 'Accessor' => 'QUACKBEHAVIOR', 'Restricted'
+ => 1 );

1; # modules need to return true

Is that fast enough for you?

Implementing protected fields is somewhere on the TODO list for Class::InsideOut. However, if all you want is public/private, the syntax is similarly short and very readable:

package My::Class;
use Class::InsideOut ':std';

private FLYBEHAVIOR   => my %FLYBEHAVIOR;
private QUACKBEHAVIOR => my %QUACKBEHAVIOR;

sub new { register( bless \(my $scalar), shift ) }

1; # modules need to return true
