Putting these functions in a 'functional' module (maybe the math module would be better?) has been suggested, but I haven't found anything that indicates that the matter is settled. Sending expressions of interest and use cases could make the final decision more rather than less favorable to the NumPy/SciPy community. There's also a plan to restructure the standard library and possibly reduce the number of library packages included in the standard distribution for Python 3.0. # Steve _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
