I really don't know. I tried everything I could think of.
I suppose defensive coding is a habit you get into when writing code, as
are copious comments and the use of 'highest common factor' language
constructs, in case the poor sod who has to maintain it after you are
gone doesn't actually understand regexp or WHY. I know I never have :[-)
Its always taken less time to do it another way, than really learn the
syntax.

Ineptocracy
(in-ep-toc’-ra-cy) – a system of government where the least capable to lead are elected by the least capable of producing, and where the members of society least likely to sustain themselves or succeed, are rewarded with goods and services paid for by the confiscated wealth of a diminishing number of producers.
