What do you lose in practice when you choose a statically-typed language such as Scala (or F#, Haskell, C#) instead of dynamically-typed ones like Ruby, Python, Clojure, Groovy (which has macros or runtime metaprogramming capabilities)? Please consider best statically-typed languages and best (in your opinion) dynamically-typed languages...

I can't seem to get JSON.pretty_generate() to actually generate pretty output in Rails. I'm using Rails 2.3.5 and it seems to automatically load the JSON gem. Awesome. While using script/console this does indeed produce JSON: some_data = {'foo' => 1, 'bar' => 20, 'cow' => [1, 2, 3, 4], 'moo' => {'dog' => 'woof', 'cat' => 'meow'}} som...

I'm writing a simple Qt4 application in Ruby (using qtruby) to teach myself both.
