Hmm, for me the second paragraph you cite describes a three-step
situation:
1. Set a context property in the `\with` block to value 'foo'.
2. Change the value with `\set` to value 'bar'.
3. Call `\unset`.
Your test code omits the `\set` command, which is slightly different.
Anyway, both situations don't work; I would call it a bug.
