Clever, but ugly, and likely inefficient to use by default. May be a  
good solution for some dynamic situations.

Minor correction: window.foo(1, 2, 3) is equivalent to foo(window)(1,  
2, 3)

And it's worth noting that they're not strictly identical, because  
the order of evaluation is different, since "window" and "foo" are  
referenced in different order.

As it happens, I'd rather lose this feature of Dylan and make it so  
that window.foo(1, 2, 3) is equivalent to foo(window, 1, 2, 3), which  
I think would be much more useful and widely applicable (no pun  
intended).
