Those are my
guidelines, for my
code. Guidelines I enforce on myself, not on anyone else.
Having comments, POD or variable names in more than one
language isn't worthwhile, and if a language has to be picked,
English it is. And while I don't mind posts in non-English
languages, I've serious doubts about the usefulness of
postings that use a different language in each sentence
(other than translations, quotes, or making a point).
The main reason I published the guideline was not to have
others copy my guidelines, and use my coding style. The
guidelines raises a number of points, which I recommend
everyone to think about.
