PR. I removed the test changes from the patch as those don't work as Jaap mentioned.

Indeed, I have not thought on the cases, where the if value: can be None.
Note:
See TracTickets
for help on using tickets.
This would be easier to review if it was a pull request.
In the patch I see at least one case where the
ifcondition should not be eliminated because it also needs to catchNonevalues.
