C binding with D function

[Adam D. Ruppe via Digitalmars-d-learn]

A fun project might be to use D's reflection to automatically 
generate any C binding translators to a nice D interface and the 
Ruby file to access it.

I did something similar back in the day for PHP and JavaScript... 
it would be kinda tricky to do it with best efficiency, but 
getting it to work just conveniently would be fairly easy.
