[Numpy-discussion] Chararray depreciated?

Also noticed that

http://docs.scipy.org/numpy/docs/numpy.core.defchararray.chararray/

lists a number of methods that are really applicable.  For example 
"sum".  This is a side effect of course of chararray inheriting from 
ndarray, and the documentation isn't "wrong" -- chararray has a "sum" 
method, it's just that it doesn't make sense and you get:

   TypeError: cannot perform reduce with flexible type

when trying to run it.

I suspect fixing this at the implementation level may be too 
difficult/dangerous, but for documentation purposes, is there a way to 
explicitly list the methods for the chararray class?
