A problem with D contracts

The problem is that you can put any kind of code inside D contracts, this will make them them very to analyse automatically. The restricted semantics is a way to avoid this.

I have used Python lazy/eager list comps, and I think they decrease bug-count and speed-up coding. In the past I have explained why (mostly because of psychological chunking).
