This sounds pretty cool, and the suggestion from Timothee also 
makes a lot of sense.

Is there any way we can rig this to behave as if it were a CTFE 
invocation?  It could be treated like an intrinsic up to the 
point where we have powerful-enough CTFE to replace it.  I'm 
still not sure if Walter would be OK with this, but I figure I'd 
mention it, since it could give us something really nice without 
having to wait for CTFE to get good.
