It's probably true in general, but I suspect a fair amount of work also went into getting the Python implementation correct, since there are things in there that are tricky regardless of the implementation language (I'm especially thinking of the TextOWrapper seek() and tell() methods). (and there are still bugs in the Python implementation btw.) Indeed, I'm sure a lot of work went into the Python implementation - and hopefully that work *saved* a huge amount of work when doing the C implementation. That's why people prototype things in Python, right? :) So it seems to me that keeping the Python implementation is useful for CPython, since if it made working on the C implementation easier in the past, it will probably do so again in the future. Basically, my point is that maintaining C and Python versions is *cheaper* than just maintaining the C version alone. The stuff I said about other VMs is true too, but it doesn't seem like anyone here is going to be convinced by it ;) (and I haven't spoked to any developers for other VMs about whether they really want it, anyway). _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4565> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
