repl: syntax highlighting, auto indenting and param autocomplete

[hemanth]

What is the problem this feature will solve?

Enhance the REPL to have:

1. In-line syntax highlighting
2. Expected parameter list for any function.
3. Auto-indentation.

What is the feature you are proposing to solve the problem?

I always liked how bpython REPL behaves:

Maybe node REPL can be something similar?

What alternatives have you considered?

Just a note, I've added syntax highlighting, auto indentation and parentheses matching to REPL written in Node.js and written a blog post Handling auto-indentation in Node.js REPL. So I think that this is doable in user space similar to IPython.

Auto-indentation may be challenging in JavaScript syntax, though. It requires a partial parser that will not choke on not completed code. But maybe creating (or borrowing) from Marijn Haverbeke's CodeMirror will be doable.

Sounds like a nice and challenging project that will improve the usage of Node.js.
