I just did gem install coltrane, then tried running the coltrane cli and I got this error:

It's because the match? method doesn't exist on your Ruby version (2.3.0).
Could you update to >=2.4?
Thanks for reporting tho, I'm gonna try set some minimum ruby version on the gemspec or maybe fix this method so it works with previous ruby versions.
