`#[must_use]` for associated functions is supposed to actually work In the comments of (closed, defunct) pull request #54884, Mazdak "Centril" Farrokhzad noted that must-use annotations didn't work on an associated function (what other communities might call a "static method"). Subsequent logging revealed that in this case we have a `Def::Method`, whereas the lint pass was only matching on `Def::Fn`. (One could argue that those def-names are thereby misleading—must-use for self-ful methods have always worked—but documenting or reworking that can be left to another day.) 2018-10-12 06:10:37 +00:00			`let _ = <() as std::clone::Clone>::clone(&());`
