I've had this issue bounching around in my head for 
some time.  I don't intend for the benchmarks to
become
confounding, arcane messes just to require the
language to perform the right number of steps.

I wonder if it would be better to allow the compiler
to perform any optimizations it wants, and just use
much larger input files?
