For the most part, solutions on my site should be written first to be
fast, second to be memory economical, and probably none were really
written to be conservative in "lines of code", since I just added that
metric very recently.  I would probably reject a solution if I felt it
was a flagrant memory waster, since you can't really get away with
that in real life.  I'll see what I can do about improving the test
descriptions to reflect these criteria more clearly.

I'll try to add more examples of "straightforward" code, especially
for the cases where an optimized solution uses noticeably more locs,
or isn't clear.

I think that would be ideal.  I would certainly need some help on
that one though.  I don't think I could do justice to even a small
application written in 20+ languages.

I think that like all benchmarks, mine should be taken with a grain of
salt too, but if nothing else, it continues to be a good learning
experience :-)

Thanks for your input.

Cheers,
Doug
