On dynamic-type languages, the actual data types passed can affect
performance dramatically.  That adds to the difficulty of realistic
benchmarks: appart from a realistic codeflow, you have to use
realistic data, at the very least regarding types.  Remember, `nil` is
a type in itself, and a very special one.  It's not surprising that
replacing "unknown values" with a set of nils invalidates any
