Cannot override existing name

[mottosso]

The error produced when Qt.py is attempting to override members that isn't officially part of a binding, but for one reason or another is there anyway.

AttributeError: Cannot override existing name: PySide.QtWidgets # 
# Error: AttributeError: Cannot override existing name: PySide.QtWidgets # 

Solution

Offer the user an option to disable this check.

$ export QT_ALLOW_OVERRIDES=true
$ python -c "import Qt"

Alternative

Another option is to disable run-time checking of this kind altogether, and save it for testing-only. These things do not change at run-time, and are unlikely to change across bindings and versions of bindings.
