Thanks!  I thought it was cute.  It was just something that occurred to me as I was reviewing some existing code.  The intent wasn’t to use `subdirs` outside of the assert statement, but I’m warm to it because it means I don’t have to do wasted work outside of the assert statement, or repeat myself in the assert message part.
