     This is the default implementation for backtick: which gets called when using the backtick syntax.

     Gets translated to the following message send:
           self backtick: \"cat README\"

     Which allows for custom implementations of the backtick: method, if needed.
     This default implementation works the same way as in Ruby, Perl or Bash.
