Therefore it would make sense to implement a general metadata facility for D and use *that* for defargs. C++11 has annotations, so that's the place to start looking at. D has already enough of those pesky special case features, let's not add yet another one at the expense of a more general metadata/annotation mechanism which eventually would be added anyway due to popular demand. Yes, I suggested this as a possibility above, but nobody commented. It seems like it might solve 2 problems with one stone ;)
Whilst I agree a metadata facility is an interesting topic to look into, I think default arguments for functions is a poor motivating example.
