than eagerly instantiating all of the canonical values in the result
with variables, we instead walk the vector of values, looking for
cases where the value is just a canonical variable. In our example,
`values[2]` is `?C`, so that means we can deduce that `?C := ?B and
`values[2]` is `?C`, so that means we can deduce that `?C := ?B` and
`'?D := 'static`. This gives us a partial set of values. Anything for
which we do not find a value, we create an inference variable.)
