Sure, I was just wondering if it was possible at all with an alias. I 
expect not.  That's rather like asking for square circles but you don't 
know until you ask, there might be some option or something whereby a 
function is instructed to grab an alias at runtime sorta the way the 
value of a variable is grabbed at runtime.  It sounds like something 
that could be doable even it it isn't actually implemented right now.  
With interpreted code I'd expect it is theoretically possible.
