What Joe is trying to do is to map the Obj-C method invocation syntax  
to Erlang for his Cocoa bridge. Granted,

[self performSelector:@selector(foo) withObject:nil afterDelay:0]

looks much better as

performSelector(self, selector:foo, withObject:nil afterDelay:0)

than

performSelector(self, [{selector, foo}, {withObject, nil},  
{afterDelay, 0}])

Here's a kicker, though... How are you going to handle  
performSelector:withObject:withObject: with the new and improved  
syntax? You can easily handle it with a list tuples, though, and you  
can use a tuple list to distinguish between the order of arguments as  
well.
