I remember changing a compiler message to HP aC++ to quote the C++ standard verbatim, because at the time aCC was the only compiler doing template dependent name lookup according to the standard, so we kept receiving bug reports.

Moral of the story: sometimes, explaining why you are doing something may require hyperlinks, just saying it's wrong is not convincing enough.

The error messages in XL and Tao3D are terrible. I'm ashamed :-)
