<div>Dear list members,<br></div><div><br></div><div>In the Racket reference under "reflection and security" they give the functionality of "impersonators". As far as I can see there is no mention in the Guide. I can see what they do, but I'm unclear what they are used for. Could someone give me a relatively simple example of where and what they would be used for.</div>
