Section 1.1 mentions PLT. Is this obsolete? It is at least confusing or someone who does not know Racket history.

At present the warning about an inadequate test is not a clear as if could be, and is mentioned only after the instruction to modify the code. -- hendrik -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
