Remember `^-` kethep? We will use `^-` as a _fence_, a way of making sure only data matching the appropriate structure get passed on.
```hoon {% copy=true %}
:: Confirm whether a value is greater than one.
:: Confirm whether a value is greater than one by return 1 (if no) or 0 (if yes).
|= a=@ud
^- @ud
?: (gth a 1)
%.n
%.y

**This is the correct way to define a gate.** Frequent annotation of type with `^-` kethep fences is _essential_ to producing good Hoon code. From this point forward in Hoon School, we will hew to this standard.
