Yeah, but do you propose to make local names visible inside the anonymous
function, or not? If you do, you open a big can of worms for implementations
(recursive nested functions, need I say more?), if you don't, BLL can still
do things that anonymous functions can not. Anonymous functors could help
some, but their syntax won't be quite as compact as your example above.
