Possibly Syntax Issue

[kylecook80]

I attempted to compile this code:

pub fn set_game_state<T: GameState>(&mut self, state: ~T) {
  self.state = state;
}

It gave me the error:

src/game_window.rs:37:18: 37:23 error: mismatched types: expected `~game_state::GameState:Send` but found `~T` (expected trait game_state::GameState but found ~-ptr)
src/game_window.rs:37     self.state = state;

The following code did compile:

pub fn set_game_state(&mut self, state: ~GameState) {
  self.state = state;
}

I was made aware on the IRC Chat that both of these snippets of code should have worked.

Didn't see that my previous issue got closed! I apologize for the duplicate.
