Daniel Keir Haywood commented on ISIS-2940:
-------------------------------------------
I see also that the original return type of `List<T>` seems to become converted
to a `Can<T>`. This makes me a bit nervous - I recollect that these have (or
at least used to have) different semantics.
> wrapper's call to filterIfRequired results in an empty collection being
> converted to null.
