> Jazzdev, where is the 'pr behaviour problematic?
I'm writing an HTML package. I'd like it to work as follows:
(pr "Some more stuff")
I'm experimenting with the idea that calling pr shouldn't be necessary, so the tag expansion eval's everything and if it gets back something non-nil then it pr's it. I'd like to still allow pr to work also, but since it returns non-nil then some things get output twice.
I want the user of the HTML package to use standard stuff, so having prnil is awkward. Allowing pr inside these tags isn't necessary. I'm just playing around and trying to see what feels natural to use.
Using pr to print something without changing the semantics of a functional program makes sense in theory, but in practice it doesn't see useful. Have you ever actually done it?
