That works. It's still a reasonably low proportionality constant and most
uses of a foreach form would have required generating a closure.

I do recall some limit on the number of upvalues a C function can have. How
does this compare to the limits on the number of arguments a function can
take -- i.e., can we fit all of ... into individual upvalues?
