Using QDebug for __repr__?

[Florian Bruhin]

Hi,

PyQt seems to have hand-written __repr__ implementations for a handful
of types:

QtGui/qgenericmatrix.sip
QtGui/qvectornd.sip
QtGui/qmatrix4x4.sip
QtGui/qquaternion.sip
QtCore/qdatetime.sip
QtCore/qregularexpression.sip
QtCore/qline.sip
QtCore/qsize.sip
QtCore/qpoint.sip
QtCore/qbytearray.sip
QtCore/quuid.sip
QtCore/qrect.sip
QtCore/qurl.sip

PySide takes a different approach there, by using QDebug writing to a
QBuffer and then returning that:
https://doc.qt.io/qt-6/qdebug.html

This often results in it having much more descriptive __repr__'s, e.g.:

    >>> from PySide6.QtGui import QAction, QGuiApplication
    >>> app = QGuiApplication([])
    >>> QAction()
    <PySide6.QtGui.QAction(0x55c428114b50 text="" menuRole=TextHeuristicRole enabled=true visible=true) at 0x7f09becb1a00>

vs.

    <PyQt6.QtGui.QAction object at 0x7f09beccda20>

Perhaps PyQt6 could do something similar too?

Thanks,
Florian
