I like coaching for the (formerly known as) performance report tool. A lot!

I was suggesting "tuning" for the collection that would house the
future visualizer and the performance coach and hopefully eventually a
memory profiler. (And maybe Eli's profiler could move in there someday

> They were correct, and you conjectured correctly. We conflated 'optimization' with 'performance gains.' As everyone knows who has been around real compilers and their writers, some 'optimizations' are 'pessimizations' as Keith used to call them. And of course even when 'optimizations' reduce the running time and/or the space consumption, they aren't _optimizations_ as John Dennis used to remind us. There is a similar conflation that additional related work pointed out. People tend to confuse 'analysis results' with 'can do optimization'. This is certainly not true for in-lining in Racket and if you know of more those optimizations, I'd love to hear about them.
