Another part of the PEP's reasoning was that this notation is difficult to understand at least partially because it is rarely encountered, so "people don't understand it" as a reason to exclude it from the documentation becomes a bit of a self-fulfilling prophecy
We know that isn't true because people already see it frequently in the tooltips for C functions. What I've observed is that after repeated exposures, users learn to treat it as noise and tune it out. I've not found a single instance where a user found it to be helpful. ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue37134> _______________________________________
