Right, thanks.

But e.g. syntax highlighting needs the semantic info to change the style of
the text within the delimiters. The analyser also needs to check whether
the two delimiters match. Like I said above, if the tool doesn't provide
enough support, you're stuck. I haven't searched for all corner cases, but
wasn't the old grammar scannable and highlightable with plain regular
expressions (except the nested comments of course).
