I may have overstated Don's point. I didn't mean that it was no longer a problem with the language - I was saying that this was an effective way to eliminate the problem within a given program.

Space leaks are certainly a huge problem with the language. For novice/casual users the runtime is effectively a black box and space leaks are a showstopper. Don was pointing out that if your process involves using these tools routinely (such as at Galois) then the problem diminishes greatly.

Do you mean, they now have a good idea where to stuff seq's in their code?

Still a bother to have to routinely run the memory profiler on your code.
