Well, a *IS* a regular chararray, and therefore a subclass of ndarray (try
isinstance). The problem isn't here, it's that the subclass doesn't have its
own .astype() method. Instead, we use the standard ndarray.astype, which
calls the __array_finalize__ method from the subclass, and this one requires
a chararray. Maybe we could implement a simple method:
def astype(self, newdtype):
But wouldn't that break something down the line ?
