Expected Behavior:

If I am in the REPL and I have a string instance x I should be able to type x., press the Tab key, and be shown the instance methods of String. If I type x.to_ and press Tab I should see all the String instance methods that start with to_.

I have this sort of started, but the issue is that it will need the Readline library for this to work, but Readline doesn't work that well in macOS, so everything I've tried fails. Definitely something to add in though.

I guess it's not possible to implement for icr. Icr has no idea about types and current context. It's not a proper REPL, rather it is a work around for REPL)

Sorry. I wish this feature too.
