Keybase proof

I hereby claim:

• I am key-moon on github.
• I am keymoon (https://keybase.io/keymoon) on keybase.
• I have a public key ASADpPLIS0B_4e6-eBuzljFGIZdIOnqw57TpV3BKgtDeXgo

To claim this, I am signing this object:

    bool IImmutableQueue<T>.IsEmpty => throw new NotImplementedException();

    public static AmortizedConstantTimeImmutableQueue<T> Empty =>
        new AmortizedConstantTimeImmutableQueue<T>(0, ImmutableStack<T>.Empty, 0, ImmutableStack<T>.Empty, ImmutableStack<Lazy<ImmutableStack<T>>>.Empty);

    private ImmutableStack<T> Front;
