ier when we used <code>gen/fmap</code> to sort a vector. <code>sort</code> returns a normal value. The function provided to <code>gen/bind</code> should return a <em>generator</em>. Notice how above we’re providing a function that returns a <code>gen/tuple</code> generator? The decision of which to use depends on whether you want to simply transform the <em>value</em> of a generator (sort it, multiply it by two, etc.), or create an entirely new generator out of it.</p>
