Well, inlining stuff sometimes makes things faster (though it sometimes 
doesn't). But I'd be seriously surprised if object allocation was simple 
enough to make it worthwhile.

I do take the point, however, that using dispatch tables without 
embellishment does preclude inlining.

It doesn't take me a huge leap to imagine including a function in the 
dispatch table that would do inlining instead of finding the appropriate 
function, though.
