To be honest I'm not sure what to feel about this. Flattered in one way but I think the features he wants could have been rolled into Module::Pluggable.
It would have been nice to have a mail either way.
I used the opportunity to do some nice speed ups to Module::Pluggable and I'm thinking of hacking in immediate instantiating just to be spiteful ;)
I've also been thinking of spinning off the code that will tell you all the inner namespaces in any given namespace. I just want to make sure that I'm not doing bad things and that nobody else has done the same.
