If Java people go to Scala, C# go to F#, where do

Question

I know a lot of Java people have started looking at Scala since it runs on the JVM, and a lot of people in the Microsoft world are looking at F#, but what does Ruby have as a natural functional successor?

In a pure FP sense Ruby doesn't lack anything, instead it has too much some may say. A functional language forces the programmer to not use global variables and other idioms so much (although it is possible to use globals in functional languages)

Answer 1

Ruby isn't as functional as say Lisp, but it is just functional enough that you can do some functional programming in a good fun way. (unlike trying to do functional programming in something like C#)

Also, it actually forces you into functional paradigms in some of its syntax, such as the heavy use of blocks and yield. (which I fell in love with after learning Ruby).
