Probably it could be made faster by working a little with InstructionSequence https://ruby-doc.org/core-2.4.1/RubyVM/InstructionSequence.h... and creating a "compiled" file to save the parsing time.

I played with it on the day they released Ruby 2.3. It's not meant for distributing code across machines and it could fail on the same machine after some updates. It's probably not worth it to shave 152 ms on an interactive command.
