I have been looking at python and pandas (python data analysis library) for ideas and on how to extend the new python->J interface. I was amused to read the headline on the pandas home page:
*** This is a major release from 0.21.1 and includes a single, API-breaking change. We recommend that all users upgrade to this version after carefully reading the release note. The only changes are: The sum of an empty or all-NA Series is now 0 The product of an empty or all-NA Series is now 1 ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
