Sadly, there are none.
The PolyOperations addon has some caveats, as
I already found the hard way.
In the end it is not so complex, but I know first hand that it looks quite daunting.
The first thing one has to understand is the fact that first we need to "create" and "set" source
and
destination container – and we need to retrieve the result in the end from the container.
The ID for retrieving is given in an array as last parameter in the CALLFUNCTION.
These are the base tricks you have to wrap your head around.
And just use the dict based version. It's easier than the array based one.
