I see. The only problem is that very few people seem to use std.bind; 
there are few interesting examples of arbitrary partial argument binding 
that need formalization. The one good example I know of is those float 
vector permutations, but nobody in their right mind would use a delegate 
for that!

That all makes it even more appealing to stick with a five-liner in 
std.functional that gets currying into the bag (which is a useful and 
low-hanging fruit) and call std.bind history. Makes sense?
