…thiaskrgr Revert: or_fun_call should lint calls to `const fn`s with no args The changes in rust-lang#5889 and rust-lang#5984 were done under the incorrect assumption that a `const fn` with no args was guaranteed to be evaluated at compile time. A `const fn` is only guaranteed to be evaluated at compile time if it's inside a const context (the initializer of a `const` or a `static`). See this [zulip conversation](https://rust-lang.zulipchat.com/#narrow/stream/122651-general/topic/Common.20misconception.3A.20.60const.20fn.60.20and.20its.20effect.20on.20codegen/near/208059113) for more details on this common misconception. Given that none of the linted methods by `or_fun_call` can be called in const contexts, the lint should make no exceptions. changelog: [`or_fun_call`] lints again calls to `const fn` with no args
