Why does Lisp need to be slower than c?
jws: The premise is only mostly true.See: How to make LISP go faster than C, http://docs.google.com/gview?a=v&q=cache:pJg0zHyA8s8J:ww...As an example, consider C pointers. The compiler never knows if two objects passed by reference are going to overlap in memory, so it can't do certain optimizations that seem obvious to a human that "knows" the pointers won't overlap.
