I think more naturally in D code rather than spec-ese (in other 
words, I find writing the implementation and usage examples to be 
a LOT easier than abstractly describing it), so it might help if 
you were to offer some specific suggestions.

Generally speaking, it'd be great if we could see you as a 
co-contributor rather than an obstacle.
