          On the "We're not worthy" scale, this rates as 3 bows:

     |                 |                  |               
     o        o___     o         o___     o         o___   
     |       /         |        /         |        /      
    __\    __\        __\     __\        __\     __\    


Hat's off to all involved, from the compiler writers to the benchmark
writer.  You guys just rock, individually, collectively, and globaly.

In the vast majority of cases, I would be more than happy to trade off
30-40% slower execution for 1/2 the code size.

However, this really isn't a fair comparison.  Who knows how many man-hours
went into sizzling the C version.  Or the C compiler/optimizer/etc
etc etc.  Throw the same effort behind Mercury and you'd really see some
barn-burning action.
