Have the authors considered the implications of requiring the `type` keyword to use a generic type, not just at declaration time? Would this open up more syntax possibilities, such as `var x T<type int>`? This might be easier to read at the expense of five more characters of typing. It also could unify declaration and usage syntax even more than the proposal.
(Personally, I will accept any syntax. It's not realistic to expect this for go2, but I would prefer if go3 ditched the C-style syntax altogether in favor of a simpler, lisp-style syntax. Such a syntax would make it easier to introduce language features like this one. Macros and metaprogramming would also be much more straightforward for users to add useful abstractions to the language.)
