Enable two checks for comparing a complex to a complex subtype instance. Split a string comparison test in two halves, replacing "a==b==a" with separate tests for a==b and b==a. (Reason: while experimenting, this test failed, and I wanted to know if it was the first or the second == operator that failed.)
