error[E0106]: missing lifetime specifier

LL | fn frob() -> impl Fn<P, Output = T> + '_ {}

= help: this function's return type contains a borrowed value, but there is no value for it to be borrowed from
help: consider using the `'static` lifetime, but this is uncommon unless you're returning a borrowed value from a `const` or a `static`, or if you will only have owned values
