Every Rubyist knows about irb. The Interactive Ruby Shell is essentially a REPL (read-eval-print loop). Type in some expression, and the result gets returned immediately. So how does Pry fit in? Pry bills itself as a powerful alternative to the standard IRB shell. But it is much, much more than that.
