I read the srfi-39 carefully. It appears that it can be more or less expressed by simple lexical scoping. For instance, ,----[ parameter ] | (define tcp-read-timeout (make-parameter 60000)) | | (parameter ((tcp-read-timeout #f)) | body) `---- ,----[ let ] | (define tcp-read-timeout 60000) | | (let ((tcp-read-timeout #f)) | body) `---- So what's the extra benifits of using `parameter'? ps. As we can see, the indention for `parameter' syntax is indented like a general procedure, which is not as beautiful as `let'(in emacs). Same for other syntaxes such as when, unless, etc. Is there a way to make them indent nicer? Or I should just live with that? -- William http://williamxu.net9.org The door is the key. _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
