[issue47145] Improve graphlib.TopologicalSort by removing the prepare step

[Larry Hastings]

Larry Hastings <larry at hastings.org> added the comment:

I'm not sure I follow you.  What do you suggest graphlib is guessing at?  I thought we were discussing what graphlib's (documented, intentional) behavior should be; if there was any guessing going on, it was us doing it, guessing at what behavior the user would prefer.

I appreciate you corresponding on the issue, but I'm having difficulty understanding what light you're shining on the problem.
