As Max said, glad to see that you're safe.

For FooIdEq: I don't think there is any need, since it can be
expressed more succinctly with the "get" function. As for FooIdIn:
this *was* a recently requested feature. Maybe we can get it in for
the next release. I think it would make sense to add the In attribute
to the entity itself, eg:

mkPersist [$persist|
Person In
    name String
    age Int

Any objections?
