The test is fair in the sense that it computes the same value, but unfair
in the sense that this is not a typical SML program, nor a program that is
susceptible to the kinds of optimizations towards which MLton has invested 
time and effort.

I doubt this has any significant affect on run-time performance.

I think that would be more instructive than counting instructions.
