Given overridden descriptors D = d[i]. 1. Find D*, subset of D: returnType(d* from D*) <: returnType(d) for each d from D. Always prefer var to val. 2. Prefer non-flexible return type to flexible. Check for var/val overrides properly (NB: this will report PROPERTY_TYPE_MISMATCH_ON_OVERRIDE for all properties, not just overrides involving vars as it was before).
