Thanks for the patch!

I've added a suggestion.

Could you update also the unit tests here and here?

[cmaglie]

I didn't quite understand how to implement the tests, with a little help I can finish this part.

For updating the tests, just add the missing case Calculus Lib-main here, and update the two tests using it accordingly, you can just copy/paste and insert the new case in the middle, they are just checking the priority order.
