I was interested in Scheme a few decades ago as a small Lisp which I'd have to implement myself. I could do tail-recursion. But returns being first-class objects -- ouch. I did not have the resources or methods to implement that efficiently. Machine too small, and garbage-collection time wa already critical. Better methods are known now. I'd have an easier time of it now, but now, I wouldn't have to. -- hendrik -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
