The more I get into ruby, more I realize the power of "irb". Long time ago, when I was developing in Visual Basic and Access, I use to use the "Immediate Window" (in Microsoft's terminology) very effectively. The whole Ruby environment is beginning to remind me of that. If anyone can point me to irb Power User Link(s), I will greatly appreciate it. Any other links to interactive development tools are quite welcome too. At the same time, I want to be aware of some of the best practices that more experienced Ruby developers have gathered, and be able to leverage that knowledge. Thanks.
