Hi Chongkai - That makes sense - Thanks for the info ;) yinso <div>On 5/29/07, Chongkai Zhu <<a href="mailto:czhu@cs.utah.edu">czhu@cs.utah.edu </a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Check the implementation of SRFI 9 in PLT Scheme, and you will find out it is just syntax sugar on top of structs. Obviously structs have features that the SRFI 9 API doesn't export, so structs are more powerful. On the other side, if you want portable Scheme code, quite many Scheme implementations supports SRFI 9, but structs is specific to PLT.
