Nice! I thought this was going to be much harder to implement.

Do you want to add some docs to the method? I noticed Ruby has the method so copying the docs should be fine.

Alright, done.

Hmmm... why there's no travis check for this?

There is, see the checkmark next to the first commit, the second commit is just docs, so I [ci skip]ed it.

Ah, I didn't know that.

Thanks for the extra docs! :-)

Would it be possible to add this as well.
http://ruby-doc.org/stdlib-2.3.0/libdoc/io/console/rdoc/IO.html#method-i-getpass

getpass(prompt=nil)
  print "#{prompt}:" if prompt
  password = STDIN.noecho &.gets.try &.chomp
  password
end
