Bigloo isn't Scheme per se. To achieve such numbers, you're programming  
in a special-purpose language, especially when it comes to floats. You  
write (fp+ ...) everywhere. In Bigloo you declare types at module  

Chez achieved this kind of efficiency in 1993 (without all these  
hacks). Bruce Duba and I showed our systems hacks at Rice that their  
claims were wrong. But boy we had to bend over backwards to get Chez  
-o3 to be within 10% of then-C compilers. And the very moment we went  
from ints to floats, we were hosed again (and didn't pursue it).

Stalin is supposedly even better. None of us has gotten it to work,  
though I have watched Quod use it.

Lareceny may one day be there. They always claim that they are about to  
catch up.

When I see the performance combined with the expressive power of  
MrEd/MzScheme, I will buy it.
