Aerolite:
I was surprised to learn yesterday that D does not actually support Multiple-Dispatch, also known as Multimethods. Why is this? Support for this feature is already present in Scala, C# 4.0, Groovy, Clojure, etc... Would it not make sense for D to remain competitive in this regard?
I think a hypothetical way for D to become more competitive is to have less OOP ;-) D things like onCmp() for classes are ugly and not easy to write correctly. Perhaps Rust solves (avoids) such problems better, and with much less complexity (but Rust will have other problems of course, like the excessive amount of type inference, because no one designs very good languages).
