Oh - here's a slight misunderstanding. I meant usefulness and not efficiency:

I'm afraid the use case is too uncommon for "ordinary users" -- and those who are 
"type system hackers" anyway can get it done quite easily (or use Fusion -- 
reading Joel's post)...

I'm sorry, it's not my intention to discourage you and I find it great you are 
motivated to make a useful submission!

You'ld have my vote for some shiny new memory management components for example, 
such as sub heaps, strided pools, optimized block copy, etc. - if I'ld have the 
time ITM, I'ld volunteer for it myself ;-)...
