Before this commit, K2 always applied coercion-to-unit for callable references if expected type was Unit, and actual non-Unit. However, this may not work in case when actual return type is a type parameter and it must be inferred into Unit. In this commit we started to disallow coercion-to-unit for references with synthetic outer call (~ top-level in K1) AND a type parameter as a return type (both should be true to disallow). This provides better K1 consistency, while still keeping some broken K1 cases working in K2. See also added comment in CallableReferenceResolution.kt. #KT-62565 Fixed
