Looks nice, and thanks for including the mpmath code (I need to remember this as a recipe)

The changes are fine with me. My impression was that the variance is inf for lam<-0.5, but looking for half an hour on the internet doesn't give any clear statements. (var for lam<-0.5 is "not finite") Without any contrary evidence the nan in this case is fine.
