The problem with the C++ form is that it's semantically identical to a function prototype statement.  I do think it would be great if there were a common syntax to construct all types in D, but I'm not sure if "X x(a)" is it.  "X x = X(a)" is probably better.  But I'd like this to work for concrete types as well.

I must have missed the comment.  Glad to hear it!

Take a look at this lib. It does most of what I see your lib doing and might give you some ides on how to make yours work in D.

Hey, that looks interesting, certainly a lot leaner than my Quan library. The example made me laugh as it seems to be a D version of one of the examples in Quan. It will be interesting to study as I know the domain and so it will certainly help me to understand a bit more about D.

Are there any plans to flesh it out? ( though it looks pretty functional already). Seems like it could be a nice example for D.
