Nick Coghlan added the comment:
Recapping the situations that need test cases before this can be merged:
* behaviour when "help" is entered at the interactive help prompt (as the
current behaviour is correct and should *not* change)
* behaviour when calling "help(help)"
* behaviour when calling "help('help')"
* behaviour when running "python3 -m pydoc help"
In the latter 3 cases, the default site._Helper docs currently shown are not
particularly helpful.
It does make me wonder whether it might be worth defining a __help__ magic
method that completely overrides what help(obj) displays. It would limit the
fix to 3.7+, but it would make it possible to do this cleanly just by defining
__help__ on site._Helper.
