#9151: Recursive default associated types don't kind-generalize properly -------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: | Blocked By: None/Unknown | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by simonpj): I'm reluctant to change the way that associated type defaults are kind- checked; but solving #9200 will also allow this program to be kind- checked. `ToEnum` will be treated as having a CUSK, and hence will support polymorphic recursion.
