I could be wrong, because I'm not familiar with the "__signature__" attribute,
but I believe it is intended to facilitate /introspection/ of classes and
methods. When Christian said "prints", I think he just meant you get to see
what the attribute holds, not that it should be used as documentation.
You could programmatically access the attributes data, and make run-time use
of it. You can't really do that with the help() output unless you want go to
great lengths to parse it.
Sorry if I'm way off here.

Sorry, I just feel the feature is just like what help() function do in Python
https://docs.python.org/3/library/functions.html#help
an example with PyQt5
>>> from PyQt5.QtWidgets import QApplication
>>> help(QApplication.startTimer)
Help on built-in function startTimer:
startTimer(...)
startTimer(self, int, timerType: Qt.TimerType = Qt.CoarseTimer) -> int

Hi,
please re-submit your reply in a readable way.
I could read it locally, but the mailing list does not
have a readable answer from you, just my copied text.
Can you please come up with more than just "why not?"?
I need a proposal how the help should look like.
Thanks in advance -- Chris
