I think I understand how your punch card trick worked for the most part, but how'd the last line work?

He would flip the card left to right. debug = 1

I under stand the flipping. But the last line (as written) wouldn't be read correctly, so the commenting out of `;0 = gubed` would never close.

I think another commenter figured it out, and the last line would need to be on a separate card.

The last line would be on a separate card, so it does not need to be reversible.

I wonder if you could write this on one card like

  /**/ debug = 1; /*/ ;0 = gubed /**/

That's what was tripping me up. I thought the last line was on the same card, so the close of the comment wouldn't be read correctly.
