Hi,

 

I would like to use algorithms like intersection or difference to modify objects in-place. I cannot find any comment in the documentation whether it is legitimate to provide one of the input parameters as output parameter to these algorithms. Even if it would work with today's implementation, it would be helpful to have confirmation that this is not going to change in the future. If it is not allowed, I would have to instantiate and then move an additional object, which I'd rather avoid.

 

Thank you.

   Volker
