Show HN: Motif – Scala-like pattern matching with Java 8

If you stick to the same kind of subset in Scala, then compilation isn't that much worse than Java, IME. It's only when you're using a lot of implicits and/or a lot of type inference that compile times go through the roof.

(and FWIW I'd say that 2000+ classes - that's what, 600KLOC? - implies a project that should be split up with clear boundaries (i.e. separate release cycles, documented public APIs between them), if only for developer comprehensibility. How big is a Java project that provides the same amount of functionality, and how long does it take to compile? Crikey, 2000 classes...)

Some companies, like Twitter and Facebook, are doing this development pattern of mono repo... So even if there are architectural lines to be found, they are eschewing that in favor of keeping versions and APIs closer together.

I can't say I understand that strategy completely but I have also never worked on machinery the size and complexity of Facebook or Twitter.
