Probably I am not that intelligent, I probably need some months :-) But that language has many good sides, and one day I'll probably try to learn it a bit. > Mathematica is expensive but learning to use pattern matching is much easier > than learning how to write a pattern matcher and much less tedious than > reimplementing it yourself all the time (which is exactly what the OP will > end up doing). I see. This is a very old post of mine, at the bottom there are few notes about the Mathematica pattern matching syntax: http://groups.google.com/group/comp.lang.python/msg/93ce3e9a08f5e4c7 To avoid reimplementing it yourself all the time then maybe someone (you?) can try to write a good pattern matcher for sequences for CPython. With such system it may become less important to switch to a different language ;-) Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
