[SciPy-Dev] usage of inspect.getargspec ?
Fri Jan 6 21:05:36 CST 2012
For the record, I don't think you are being inappropriately grumpy. Your feedback is exactly the kind required and valued. If you think something stinks, you should speak up. Olfactory sensors can be damaged in others.
This discussion is about at least 2 things as far as I can see:
1) Using an API that allows a single callable to have different signatures and purposes
2) Using inspect.getargspec
Clearly inspect is seen as too fragile. I don't disagree. I don't weight the impact of that as highly as others in this particular case.
But, is it also felt that #1 is untenable?
