one event upon wake from sleep.

A type of list which does not allow duplicate elements. The base/inner
list type to use (e.g. `types.listOf` or `types.nonEmptyListOf`) is passed
via argument `listType`, which must be the final type and not a function.
NOTE: The extra check for duplicates is quadratic and strict, so use this
type sparingly and only:
* when needed, and
* when the list is expected to be recursively short (e.g. < 10 elements)
and shallow (i.e. strict evaluation of the list won't take too long)
The implementation of this function is similar to that of
`types.nonEmptyListOf`.
