[Numpy-discussion] boolean masks & lists

A colleague of mine just asked for help with a pesky bug that turned out to be caused by his use of a list of booleans rather than an array of booleans as his logical indexing mask. I assume this is a feature and not a bug, but it certainly surprised him: In [58]: mask = [True, False, False, Fals
