Should numpy.sqrt(-1) return 1j rather than nan?

Talking about masked arrays, I'm about being done rewriting, 
mainly transforming MaskedArray as a subclass of ndarray (it should be OK by 
the end of the week), and allowing for an easy subclassing of MaskedArrays 
(which is far from being the case right now)

What would be the best procedure to submit it ? Ticket on SVN ? Wiki on ?

Thanks again for your time !
