Unfortunately, the compiler isn't keen on them being used in types.  

"bug2.as", line 10:        (x, 0$SPF(x)) for x in 1..10;
                    .........................^
[L10 C26] #1 (Error) `x' is used in a type, so must be constant, and so cannot be assigned to.

This seems to be built into scobind.c. I'll hit it with a stick & see what happens..
