The lexer must be configurable enough to tokenize other languages than 
D. I confess I'm very unhappy that there seem to be no less than three 
people determined to write lexers for D. We're wasting precious talent 
and resources doubly. Once, several people are working in parallel on 
the same product. Second, none of them is actually solving the problem 
that should be solved.
