Issues list

Unsoundness with blanket implementation over lifetime-less marker traits A-traits Area: Trait system C-bug Category: This is a bug. I-prioritize Issue: Indicates that prioritization has been requested for this issue. I-unsound Issue: A soundness hole (worst kind of bug), see: https://en.wikipedia.org/wiki/Soundness needs-triage This issue may need triage. Remove it if it has been sufficiently triaged. T-compiler Relevant to the compiler team, which will review and decide on the PR/issue.

const blocks don't have a recursion limit or timeout, causing the compiler to freeze in an infinite loop A-const-eval Area: Constant evaluation (MIR interpretation) A-const-fn Area: const fn foo(..) {..}. Pure functions which can be applied at compile time. C-bug Category: This is a bug.
