Return the set of additional properties for the given ``instance``.
Weeds out properties that should have been validated by ``properties`` and
/ or ``patternProperties``.
Assumes ``instance`` is dict-like already.

Create an error message for a failure to match the given types.
If the ``instance`` is an object and contains a ``name`` property, it will
be considered to be a description of that object and used as its type.
Otherwise the message is simply the reprs of the given ``types``.

isinstance() can accept a bunch of really annoying different types:
* a single type
* a tuple of types
* an arbitrary nested tree of tuples
Return a flattened tuple of the given argument.

Check if all of a container's elements are unique.
Successively tries first to rely that the elements are hashable, then
falls back on them being sortable, and finally falls back on brute
force.
