You should be able to retrieve the text blob and dynamically drop it inside a <script> tag.

This works in the Chrome and MSIE 9 consoles - I didn't try Firefox yet:

var s = document.createElement('script');
s.appendChild(document.createTextNode('alert("hello")'));
document.head.appendChild(s);

As for stringifying the code, it's normally possible to call myFunction.toString() on user supplied functions.
