A test runner maintains a set of "result properties" associated with

Each property has a name (a symbol) and a value (any value).
Some properties are standard or set by the implementation.
We should clarify the semantics of attempting to set a standard
property. For example, is it legal to set the 'kind property?
I would say that is undefined.
Generally properties would be set by the implementation,
and read by the test-runner. In some cases a test-runner
might add some extra properties, but I expect that to be
rare - offhand I don't see any use case for that.
Would that cause test-runner-pass-count and friends to be adjusted?
Undefined.
What about setting the 'kind property before the test has completed?
And anyway, what is the value of the 'kind property for a test that is
in progress? I supposed it would just not be set.
Yes.

you will need much more information (perhaps located arbitrarily far
away in the program) to understand what is actually being done. Is the
property denoted by y of runner x being accessed, or is property x of
the current runner being accessed, with a default value of y?
We can pick one. I'd say here x is the runner and y the 'pname.
Perhaps we should just make these [runner] arguments required.
It's important to have a convenient/terse syntax for test suites,
but there is little value in making test-runner code maximally terse.

That was a typo. I meant to write #f.
