I remember reading this in "Arc at 3 Weeks" and being quite excited about it: The Scheme language sneakily increased the scope of the language designer's powers. From very early, maybe from the begining, the Scheme spec said that conforming implementations must do tail call elimination. The first time I read this, I thought "wait, can you require this in a spec?" Arc will see this increase, and raise it by some standards for profiling. I thought that was a great idea. Too few languages have good support for profiling. Did the idea get dropped? I don't see anything obviously related in arc.arc or in the tutorial.

I'm sure the idea didn't get dropped cause it's pretty darn important -- and it'd be a major back peddle for PG. It certainly might have been postponed, though. I wonder if PLT Scheme's profiling tools are good enough on Arc programs (or useful at all?). I hear they have pretty good ones, but haven't used them myself. Arc might be different enough from MzScheme that the information that the PLT profiler returns on Arc programs isn't so useful.
