[W/K] :: Swiss-Army chainsaw

  Swiss-Army chainsaw In early Unix days, a well-known technical paper
     analogized the lexical analyzer lex(1) to a Swiss-army knife; this was a
     comment on the remarkable variety of more general uses discovered for a
     program originally designed as a special-purpose code generator for
     writing compilers. Two decades later, well-known hacker Henry Spencer
     described the Perl scripting language as a "Swiss-Army chainsaw",
     intending to convey his evaluation of the language as exceedingly
     powerful but ugly and noisy and prone to belch noxious fumes. This had
     two results: (1) Perl fans adopted the epithet as a badge of pride, and
     (2) it entered more general usage to describe software that is highly
     versatile but distressingly inelegant.
