which is nine extra characters instead of six :)

I have to say I like it, but it needs to be commented to say that the the
hash values are irrelevant but need to be 'true'. If your code does anything
specific it needs to have a reason.

Development time is many millions of times more expensive than processor
time. Try to make it run faster /only/ if it's too slow; otherwise
make it maintainable above everything else.

Strictly, there are infinite ways. Perl is rich in that there are usually
many /sensible/ ways to express a solution. Hence, I suppose, this group's
enthusiasm: C, and even C++, cannot generate this level of enthusiasm.
