Agreed in this regard. Whenever I have to leave in the computer before I have the chance to finish something, I usually just make a comment with the string `WIP` in it: /* WIP: make sure to initialize buffer by calling function foo() */ ... the idea is that I'll remember that I left my code in an unfinished state, search for the `WIP`, get my bearings and then go off. Of course, that's easy to forget -- but impossible to forget if your WIP note is uncompilable.
