We should be doing better in this regard.  

The __array_wrap__  is being applied (correctly now) in all the linalg 
functions, so that matrices are returned if they are used.

All the ufuncs already preserve arguments. 

But, we should also peruse the code for asarray calls, save the 
__array_wrap__ method if available and wrap back the results so that 
types can be preserved.

Someone spoke of writing a decorator to do that automatically which 
would indeed be nice.

If you have examples of functions that are not being preserved, please 
report them.
