No because it's statically typed, too much work programming like that and it's not worth it for the kind of software I develop (backend of web/mobile apps), but thanks. Suggestions are always appreciated.
I found a defunct Ruby like language called Reia a couple of days ago https://github.com/tarcieri/reia/ and http://reia-lang.org/
It's object oriented and runs on the top of the Erlang VM. It maps classes on gen servers, which is pretty natural and it spares the developer all the boilerplate of creating a gen server module. Unfortunately the language designer killed it because "it's pretty bad to have two competing niche languages with nearly identical features." The other language was Elixir. However the two languages are very different. Elixir is 100% functional, Reia could have been the language to transition millions of OO developers to a functional and concurrent world. I could have used it instead of Ruby.
