Review Comment:
@Fokko, this PR introduces 3 of these decorators to make it easy to
construct predicates. This decorator replaces `__init__` with a version that
converts a string passed as `term` into a `Reference`. This makes it much
easier to create expressions, as you can see from the test cases.
The other decorators handle set predicates and literal predicates.
