The
$.
code fragments removed in this PR had no effect on the output, so I figured removing them would simplify the examples.I did not presume to know if doing the same in Perl would similarly have no effect, so I didn't modify the comments above those lines, but put a TODO there to alert us of the need to address it. If you like you can tell me how to modify those lines and I will do so.
