Resumen
Approximately 12 years ago, the Unix programming universe consisted of two linguistic cultures. One could either program in "C," or program in the "shell." The two systems were good for different things, so their capabilities were widely viewed as complementary. The revelation came that these capabilities were not, in fact, opposite ends of a single dimension, but rather the axes of a two-dimensional graph. The C programming language was good at getting down into "innards" of things, but wasn't very good at whipping things up quickly. Whereas the shell was good at whipping things up quickly, but couldn't get down into the nitty-gritty stuff. So, if those were the two dimensions of the graph, then each language stayed near its own axis, and there was this big blank area in the middle. To fill in the blank area, Perl language was developed. Right from the start Perl was designed to evolve.
