VERSION
codereview.cfg
go.env
- detect *interface case and report specific error - replaced switch with sequence of if's for more clarity - fixed isInterfacePtr: it applies to all interfaces, incl. type parameters - reviewed/fixed all uses of isInterfacePtr - adjusted error messages to be consistently of the format "type %s is pointer to interface, not interface" Fixes #48312.
