No. �It needs to be in the compiler to be inlined. �Why have you got on this hobby-horse? �It is a non-issue. �caseOf: ios not widelty used but extremely useful in certain circumstances. �This has the feeling of a religious pogrom, not a rational approach to the system. �IIABDFI = If It Ain't Broke, Don't Fix It.�

Are these two points correct?

No, IMO, definitely not.
