you are obviously correct.  however, i wrote a decoder recently which decoded
some largish text weather data.  it took around 30 seconds to run - which was
actually acceptable.  i decided to profile it, in 5 minutes i changed two
offending lines, and now it runs in under 1 sec.  my c++ version takes 3
seconds.  i think profiling is key with languages like ruby and perl.
