Not really. Part of the point of voldemort types is that no information about the type is 'leaked' outside the function. In this case, the trait 'HasGetValue' is leaked and can be used by other code.
- skohan 6y agoWhen would you want to have an interface such that nothing about the return type of a function is known to the outside world? I'm genuinely asking; I just don't understand the utility of this concept.
