I've noticed that these days the new super fast Prism parser has a parser backend that seems to work with RuboCop (see https://github.com/kddnewton/parser-prism#rubocop), but requires a bit of manual work. I've also noticed one impressive benchmark that implies RuboCop runs 4 times faster with Prism!!!

I think we should make it easier for users to use Prism - e.g. if it's present it should be used by default or something along those lines. (might also be some configuration option)

@rubocop/rubocop-core Any thoughts/ideas on the subject? //cc @kddnewton
