Perhaps the function can set a flag if it doesn't see any `return` statements. -- |

Eh, that means scanning the statement AST before semantic analysis, i.e. slow. I don't think this is a particular problem anyway, as why would one return `auto` if there are no `return` statements? -- |

To enable attribute inference on the function, or because it's a generic function which returns based on template parameters. I don't have a concrete use case so I don't think there's much priority to support this, but if it's not going to be supported, then at least the limitation should be in the specification. -- |
