Need for Speed: Using RuboCop with Prism | Meta Redux

I’ve been keeping an eye on Prism for while, as RuboCop has long been criticized for its choice of parser (and more specifically - for that parser being somewhat slow). That being said - parser migrations are always a pain, especially in a project as big as RuboCop. Early on I had to essentially rewrite RuboCop when I switched the codebase from ripper to parser, and back then RuboCop was a lot smaller. The good thing is that such rewrites can be done incrementally (I was migrating cops in batches), but it was still a lot of (boring, repetitive) work.
