I added the 'builtin' command, which did leave the labs. But I added it as a way for the "whatis" command to show a builtin, as well as allowing a way to guarantee you get the builtin on execution.

How do I get bash to print the function as (shell) source code, so I could edit it and play with it again? It was the synergy of all this stuff connected seamlessly that made it so compelling.
