Forth is has an operator M* (pronounced "M-star" for all you 
"pronunciation" types) which takes two 16-bit values and returns their 
32-bit product. I would conjecture that after the smoke clears on a 
possible 32-bit based Forth standard, that M* could change from a 
16x16=32 to a 32x32=64 bit multiply.
 
No doubt someone will say "Forth, ugh!". All I can say is, pooh on you!
