[plt-scheme] define-datatype
Hi all,
I've been EOPL by Friedman and he in page 44 of his book mentions
that define-datatype is a scheme extension. I've not been able to
use it in DrScheme. I've searched the Help Desk and I know that
there is a eopl collection but how can I use it?
Best regards,

Yes, God had a deadline...
So, He wrote it all in Lisp!
