Thank you all,<br><br>I think I need to go read some code - the webserver is probably a good choice as it seems to be getting a lot of use lately. I'd also appreciate [code reading] suggestions if anyone would care to make any.<br> <br>s<br><br><div class="gmail_quote">On Fri, Nov 21, 2008 at 8:44 PM, Matthias Felleisen <span dir="ltr"><<a href="mailto:matthias@ccs.neu.edu">matthias@ccs.neu.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <br> Well this is where units shine. You can have one data structure implementation where define-struct is implemented via lists and another one where the same structure is a true struct. And you can relink the program to get lists for one purpose and structs for another. -- And you could do this in the same program, though you'd need a translator/adaptor unit to make them work together.<br> <font color="#888888"> <br> -- Matthias</font><div><div></div><div class="Wj3C7c"><br> <br> <br> <br> <br> <br> On Nov 21, 2008, at 3:31 PM, Grant Rettke wrote:<br> <br> </div></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div><div></div><div class="Wj3C7c"> On Fri, Nov 21, 2008 at 6:15 AM, Noel Welsh <<a href="mailto:noelwelsh@gmail.com" target="_blank">noelwelsh@gmail.com</a>> wrote:<br> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Use structures and/or pattern matching (see match-lambda in<br> particular).  Using lists as structures is, I think, quite bad<br> practice.  You can get away with it for limited cases but it will bite<br> you in the arse if you change the data format.<br> </blockquote> <br> It is a worthwhile personal experiment to try using lists as data<br> structures for a while, and it is true, eventually it will become<br> terrible to maintain.
