And further, using "<code>" tags is only part of the problem. There's plenty of text/character sequences which is trashed entirely in a web-forum parser if one cannot skip parsing altogether of entire blocks of text, like this for example:

// The Regex below will (probably) be destroyed entirely in
// the web-forum, and any Array"][" square brackets would
// be as well (guess why I swapped the brackets...):


/\[\[                   # Beginning of the link
  (?:([^:][^]]*):[=:])+ # Property name (or a list of those)
  ([^\[\]]*)            # content: anything but [, |, ]
\]\]                    # End of link
/xu
