Hi all, I have just released version 0.2 of Shed Skin, an experimental (restricted) Python-to-C++ compiler (http://shedskin.googlecode.com). It comes with 7 new example programs (for a total of 40 example programs, at over 12,000 lines) and several important improvements/bug fixes. See http://code.google.com/p/shedskin/wiki/ReleaseNotes for the full changelog.
The new example programs consist of Disco, an elegant go player (see http://shed-skin.blogspot.com/2009/07/disco-elegant-python-go-player.html), a larger Voronoi implementation at 800 lines, a TSP algorithm simulating ant colonies, a nicer neural network algorithm and three compressors (Lempel-Ziv, huffman block, and arithmetic). Other than bug fixes for these programs, this release adds some important optimizations. First and foremost, inlining was greatly improved, resulting in potential speedups across the board. Second, loops such as 'for a, b in enumerate/zip(sequence[, sequence])' should now be dramatically faster (also inside list comprehensions), by avoiding allocation of intermediate tuples. Finally, basic list slicing should now be much faster. Please try it out!
