Sure, the underlying principles may be the same but I'm caught up in the
boilerplate required to make it work. To be honest, I found the
documentation difficult to assimilate because it reads like a technical
discussion of the implementation details rather than a recipe book. This
isn't intended as a criticism, obviously people learn in different ways, but
speaking from a personal standpoint, it would really help if you had code
samples for the top 5 use cases of the library. One people have working code
the pressure comes off and they are more willing to learn about the nuances.

Thanks. It did work, but the assertion led me in completely the wrong
direction.

I appreciate you getting back to me during the holiday period. Merry
Christmas to you and yours.
