Thank you for the thorough investigation, it seems clear to me now that
chararray does have a purpose and is in good hands.

The discussion began on the scipy list, but I think you addressed most

Well, then the docstrings should say that. It can be a 4-line standard
template that refers to the stdlib docs, but it would be nice to get
something other than this in ipython:
>>> charar = np.chararray(2)
>>> charar.ljust?

Docstring:
