A technique to mock "static interfaces" (e.g. isInputRange)

[Robert burner Schadek via Digitalmars-d]

+1 having a look at AutoImplement

For testing ranges, I usually use 
https://github.com/dlang/phobos/blob/master/std/internal/test/dummyrange.d
even though its internal ;-)

anyway, more and better testing always good.

p.s. I think at some point we have to build some (the perfect) 
mocking framework with dependency injection and all the other 
awesome stuff. But before that can happen we have to lose the 
fear of classes and OO. Please no OT!
