Exactly. It's unfortunate that Interfaces are still something of a red-headed
stepchild in D ~ It's not entirely clear that Walter uses Interfaces, or fully
appreciates their powerful 'contractual' and decoupling aspects. There's no need
for such tools when you're not working in a reasonably-sized team, or trying to
build some kind of extensible library (or whatever).

D interfaces have 'just enough' to make them useful in simple cases. For that,
they are just fine ~ there's enough functionality there. Perhaps it'll mature?
