Future of Ruby – AST Tooling
There are already some techniques capable of doing just this, by combining Parser with Unparser, but of course such things can only be done on Ruby files read in rather than in a REPL session which is where a lot more fun could happen.

ASTs in Ruby - Node Pattern and Introducing RuboCop
Oh, and that regex bit? Remember how we have Rubular for regex? We have the NodePattern Debugger for ASTs which you will find incredibly helpful, in fact you might open it now and try out some of these examples to make sure I'm not pulling a Fast one. (No, I'm not apologizing for that one.)

Future of Ruby – AST Tooling
Some of these tools have even already been wrapped, like Jonatas's work on FFast which works on top of NodePattern and some of RuboCop's previous work. Really the only things between us and this future is a bit more wrapping and polish, as well as integrations into something like VSCode.
