Почему единственный интерпретируемый язык в штатной поставке OpenBSD это Perl?

    Assume you need a script language, because writing everything in C is
    cumbersome.

    What are the choices ?
    - you need something under and acceptable licence, so python is out.
    (Artistic Licence is "close enough");
    - you need something that builds everywhere, so python is out (hard to build
    without dynamic libraries, that was vax...);
    - you want a modicum of security, so shell and tcl and php are out.
    - awk would kind of work, except it's not that readable, and it wouldn't
    scale up to some of the things we use perl for.
