Who has the fastest machine? 😄

README.md

Challenge

Include the Maven / Gradle dependency io.vavr:vavr:0.9.1

and run the code below. Your fastest run counts.

(Note: this is not some kind of benchmarking, it is part of the 'challange' to use it as-is.)

Write the result at Twitter as a reply to: https://twitter.com/vavr_io/status/910550358635761665
