A shell colon does nothing. Use it anyway
I use the null command all the time when I start typing something out but still want it in the history so I don't have to type it out again. Jump to the start of the line, add a colon, enter to put it in history and then do whatever else you were going to do, and later on jump back and just remove the first character to actually run it. I never thought of using it for the side effect of evaluating the arguments though, that's clever!
