This is the only decent reason given for numbering and, 
considering dmd's not localized yet, is far from being a need.  
I'm all for putting better explanations of error messages 
somewhere online, but Walter's right that keyword search is a 
better interface these days and numbering is unnecessary overhead.

If there are such help pages for error messages, there's 
basically no advantage to numbering over string matching for the 
error messages and an additional cost of keeping track of all the 
numbers.
