Hi folks,

I can't get an example to evaluate when it has define in it. I've tried lots of stuff. The example in the scribble documentation works, but that uses typed racket. I don't want to use typed racket:

```
@examples[#:eval my-evaluator
(define (positive-integer? x)
(and (positive? x)
(integer? x)))]
```

Earlier I tried:

```
@examples[#:eval my-evaluator
(define (positive-integer? x)
(and (positive? x)
(integer? x)))
(positive-integer? 42)]
```

DrRacket says "examples: exception raised in example

error: "define: function definitions are not allowed in the interactions window; they must be in the definitions window""

Thanks for your help.
