Re: Re: ?int - what's the representation?

Right. Note however that this would only work when using the value with the 
type ?int. For instance, if you want to put it inside a Collection<Object> or 
pass to a generic method <T> void foo(T); I don't see how the wrapping can be 
avoided.

The optimization would be interesting nonetheless.

And how did it go?

I guess it would be easier to do it during compilation, when you have all the 
typing information.

By the way, what happened to your project to extend Nice with pattern matching 
on fields of the arguments?

Cheers,
