74−- `?:` (pronounced "wut-pam") is the simplest "wut" rune. It takes three children, also called sub-expressions. The first child is a boolean test, so it looks for a `%.y` or a `%.n`. The second child is a yes-branch, which is what we arrive at if the aforementioned boolean test evaluates to `%.y`. The third child is a no-branch, which we arrive at if the boolean test evaluates to `%.n`. These branches can contain any sort of Hoon expression, including further conditional expressions. Instead of the `?&` expression in our `%say` generator above, we could have written

86−- `?!` ("wut-zup") is the logical "NOT" operator, which inverts the truth value of its single child. Instead of `(lte n 100)` in our `%say` generator above, we could have written `?! (gth n 100)`. Again, this would be bad practice, we only present this as an example.
