Sure, D should have monads as soon as Haskell programmers are able to 
explain this concept to 'normal' programmers (and no cheating such as 
the classical handwaving, this is a way to wrap side effects..)
So probably never then.

That said, I agree very much that allowing debug output and memory 
allocation in pure function makes them much more useful while keeping 
their 'purity'.

So I vote +1
