As I recall, at one point before the public release of Go Russ made a
pitch for changing &T{} to (*T){} as that would be more consistent:
just as T{} creates a value of type T, (*T){} would create a value of
type *T. But even though it was more consistent nobody really liked
it and we stuck with the &T{} syntactic sugar.
