Seem reasonable that there should be some way (any kind of way) to tell the 
compiler "hey, I know what I'm doing here; step away from the heap!".  After 
all, heap allocation (and subsequent GC load) is one of the more expensive 
things a chunk of generic code can do. It's the#1 underlying cause for why 
many people feel Java is slow :p
