But there are already quite a few methods in NumPy that doesn't modify the 
array in-place (swapaxes, flatten, ravel or squeeze, but I guess many more).
I'm personally an addict to encapsulate as much functionality as possible in 
methods (but perhaps I'm biased by an insane use of TAB in ipython console).

Cheers,
