in reply to Perl as Language
C is to Perl as Latin is to EnglishI disagree. C is far from a dead language, and C has orders of a magnitude more "speakers" than Perl has. In fact, if you take two programmers, the language they most likely share common knowledge of will be C - just like the English will be the most likely language two people share common knowledge of.
C is to Perl like English is to Esperanto.
