Numpy uses + for elementwise addition, and a function called concatenate for concatenation. If Python lists used a separate concatenation operator, then Numpy arrays could use that for concatenation.
Actually it couldn't, except for the special case of concatenating along the first axis. The concatenate() function allows specifying an axis. There's also the problem that applying a concatenation operator to a numpy array of Python sequences would be ambiguous -- does it mean concatenating the arrays, or elementwise concatenation of their contents? -- Greg -- http://mail.python.org/mailman/listinfo/python-list
