[Interest] Qt 5 -> 6: In QQmlEngine, Qt.Checked, etc. are no longer available

> Right, normally when evaluating a script, any error can be caught and reported however you wish, but this does not work when the script execution is trigger through a signal connection. In this case, when using QJSEngine, errors are always printed to the standard out, whereas the QQmlEngine allows reporting these through its "warnings" signal.

Well, I would like to see a bug report with a minimal reproducer for 
this. How do you produce a signal connection in pure JS?

best regards,
