I've been ranting on and off for years about the need for a good REPL when learning a new language or exploring a new concept. If I can't dig into the objects and poke around at how the individual pieces actually run I find it extremely hard to get a handle on these things at scale. I've always assumed it was more a "me" issue, and so I've attempted to work in the more "normal" manner, but with pretty poor results. I've all but given up on Python due to its lack of a decent REPL and gone back to Ruby, where at least I have pry to dig in with as needed.
