R.I.P. SimpleRewriter. If anyone needs it resurrected let me know. This leaves LocalRewriter (the default) and the new TrivialRewriter, which is for use only with the new in-place spilling framework. This framework appears (if you squint just right) to be basically functional now, but it produces awful code. If you w...
