For this patch, a simple search was performed for patterns where there are two types (usually an LHS and an RHS) which are structurally the same, and there is some result type which is resolved as either one of them (typically LHS for consistency). We change those cases to resolve as the common sugared type between those two, utilizing the new infrastructure created for this purpose.
