Ricardo,
As mentioned in #moose, I very much like this idea. I do have a few
questions ...

The initializer may be a coderef or a method name (referring to a
method on the
instance.) It's called like this:
$instance->$initializer($value, $name, $callback);
What is $name for again?
The callback, when called, will set the instance slot to the passed-
in value.
It makes it easy to have your initializer do the "hard" work
without having to
worry about going through the several chains of methods needed to
set a slot
value. The example in the tests should look something like this:
package Example;
use Moose;
has foo => (
is => 'rw',
initializer => sub {
my ($self, $value, $name, $callback) = @_;
$callback->($value * 2);
}
);
I wonder if callback could be optional? And if it is not called, then
it will just use the return value of the initializer sub?
I think, but have not tested, that this will also work:
package Example;
use Moose;
has foo => (
is => 'rw',
setter => 'set_foo',
initializer => 'set_foo',
);
What exactly would that be useful for? I am not sure I understand
without seeing an example set_foo.
