Explore the possibility to add a command to copy evaluation result

It could be very helpful to have a command to copy IRB's output without manually selecting a (potentially huge) chunk of text. For example:

copy User.all.to_a # copies and echos all users
copy User.all.to_a; # copies and doesn't echo all users
copy _ # copies the previous output value

Things to consider:

We cannot rely on any non-default Ruby gems
We may use system commands if they're widely available, at least among UNIX-based systems

macOS only

I mimic this by adding these two methods to my ~/.irbrc, which use the pbcopy and pbpaste command line utilities.

# Copies the input to the user's clipboard.
def pbcopy(input)
  str = input.to_s
  IO.popen('pbcopy', 'w') { |f| f << str }
  str
end

# Returns a string containing the contents of the user's clipboard.
def pbpaste
  `pbpaste`
end
