    fn method_call_with_result<R, E, F>(
        &self,

}

A trait to help the code generation a bit tidier.

We’ll implement it only for the MutexHandleMap which asks for FnOnce(&mut T) callbacks, but we’ll give ArcHandleMap very similar looking methods, that accept FnOnce(&T) callbacks.

When generating the code in the to_rs_method_call macro in macros.rs, the code will be lexically identical.
