+Optimization
+------------
+
+Once the meta-interpreter has verified that it has traced a loop, it decides how
+to compile what it has. There is an optional optimization phase between these
+actions which is covered future down this page. The backend converts the trace
+operations into assembly for the particular machine. It then hands it back to
+the frontend. The next time the loop is seen in application code, the optimized
+version can be run instead of the normal intepreter!
