JetBrains’ Dmitry Jemerov on Scala
I can rave about JetBrains' IntelliJ IDEA until the cows come home - it is simply a superbly executed and very well focused product. What I found especially interesting is the following quote on Scala becoming a dominant language for the JVM:
I don't believe that, however: Scala is very complicated, it's tricky, and has a lot of surprises and edge-cases. I would say that Scala is at least as complicated as C++, and with C++ you need a hundred-page style guide before you even start writing C++ code, otherwise you'll end up writing C++ code that nobody will understand.
Scala gives an impression of great elegance and simplicity at first glance but the same goes for Perl as well. The one feature of Scala I really like is the language-level support for traits which allow reusing multiple concrete implementations similarly to multiple inheritance, but with fewer gotchas.
