All due respect, but I disagree. The word sic is a Latin adverb meaning 'thus, in this manner, in this way'. There is nothing in the word that intrinsically points to language or quotation.

And when using the Latin word "sic" in English writing it is generally understood to indicate a decision to quote something verbatim in lieu of correcting a percieved mistake. If you want to write messages in Latin then I suppose we should hold you to also writing Perl in Latin as well!! ;-)
