I understand that Python depends on complex built-in functions, and external libraries such as numpy, for it to be used viably. But I'm also interested in using such languages directly. Take the jpeg benchmark. Of course both Python and my language are hopelessly slow and impractical compared with a C implementation, but this is still a useful test (and in fact the interpreted version was used to more easily develop a streamlined decoder that was then back-ported to C, doubling its speed). (The Python version of that program is here: http://pastebin.com/cHx3UhQb. It should work with any Python.) For example, suppose you wanted to do crude animation by loading a series of small 640x480 images. Loading such an image gives you the following frame rates, excluding the extra overheads of displaying the results: Python 2.7: 0.33 fps Python 3.4: 0.25 fps PyPy: 0.55 fps (don't known what version) Mine: 3.77 fps You can't really call the first three animated (more like a slide show), but 4 fps just about cuts it! Sometimes pushing an interpreted language a bit further can be useful (hence the existence of the PyPy project). -- Bartc
