The combination of the simple optimizations that Sam suggested, as well as replacing the runtime parameterization with syntax-parameterize, results in about a 30x speedup.
Hi Danny, Cool stuff, but you might want to compare to this example in PyPy: http://morepypy.blogspot.com/2011/04/tutorial-part-2-adding-jit.html If you get numbers, please share them here!
