should not compile?

should not compile?

No, and there is no way to express such requirements.

Can I ask why not? When an interface is implemented, the compiler knows if the contract is met or not. Similarly the compiler knows when a variable is not initialized. Why is this diffferent?

[bashor]

Right now there is no way to say compiler that an instance passed to lambda is not initialized and compiler don’t track this case.
