Hi,<br><br>I'm trying to use the new struct datatype, but I keep getting the following error<br><br>struct: illegal use of signature form in: (struct posn (x y))<br><br>when defining the struct. The old way of defining a struct ((define-struct ...)) works though.<br>
<br>I'm running DrRacket version 5.0.1 on Ubuntu 10.2 that I built from source.<br><br>Any ideas on why the error occurs?<br><br><br><br><br>
