The post raises a few good points -- those are real problems in using Scala -- but the problems are mostly a result of the compiler targeting the JVM as its primary backend. Obviously, a JVM-based language can leverage a rich infrastructure of libraries, but it also will have to deal with the fact that the JVM is primarily designed for Java, not as a more general backend (such as the LLVM or the CLR).

(That the compiler is slow has other reasons, but is also something that they've been working on simultaneously for 2.10, so it's not as though that has been pushed aside by macros.)
