You'll always need a concrete type in order to get the trait method
for that type. Something like this may work for you though:
trait A {
fn foo(Self);
}
impl A for int { fn foo(a: int) {} }
fn main() {
let f: fn(int) = A::foo;
}

Suppose I have a trait T:
trait A {
fn fun(t:T); // <- [1]

Is there a way to get a pointer to the implementation of fun for a
specific T? How would I go about calling it?
(Yeah, I know I'm kinda far off the reservation.)
[1] Not necessarily an instance method, but that would be useful, too.
