I did look into this and I confirm coverity's assessment.  It should be resolved with the following commit:

This one, however, is related to the function object being passed by value, and it's intentional.  It's modeled after how std::for_each implementation takes its function object by value and returns either a copied or a moved instance of it.

As far as I know it cannot support inline lambdas unless the method takes the function object by value.
