Make Thenable an interface (not typedef) for more efficient compile time type checking and possibly better perfomance on static platforms #60

Hey, it is me again, after some AsyncBase changes Thenable typedef was broken once again, so i decided to make it an 'read only' interface for promises and streams. Since AsyncBase now implements Thenable you can do stuff like that

public function remoteRequest():Thenable<String>
{
    var def = new Deferred<String>();
    def.resolve( "yay" );
    return def.promise();
}

remoteRequest().then(function(str)
{
    trace(str);
});

Ok, now i get it, AsyncBase must be used in that case... can't see any purpose in Thenable typedef then.

There's been some changes in haxe 3.2 that might make this possible, I just need to rework things. I've got a number of other pending changes in the works for a version 2.0. It should be backwards compatible provided you're on haxe 3.2. So, stay tuned.
