I have a module where the constructor is something like:

sub new {
  my $class = shift;
  my $self = {};
  $self->{atr1} = undef;
  $self->{atr2} = undef;
  # more attributes...
  bless($self, $class);
  # ... some code to populate attribs from passed parms
  return $self;
}

I can create an object with:

use MyMod;
my $mm = MyMod->new(atr1 => 1, atr2 => 'string2');

[download]

I can get any attribute value directly with $mm->{atr1} and also set it with a simple assignment.

As some validations/actions are required before/after an attribute is set, I want to prevent this type of access, and allow it only through get() and set() methods also provided for the class.

Is this possible? Or am I doing something wrong?
