should it be?
(I have fantasies of getting to the spec sometime today)

1. because Java because C++
2. unlike other arguments, "type" arguments in <>s are optional.
3. at one point I tried to suggest a general optional keyword scheme, and you'd write foo type(X,Y)  or something if you wanted to give types
