Actually, it's rather straightforward. I already have something that  
supports dtype=(int,int,float) (far easier to handle than "i4,i4,f8"),  
I need to tweak a couple of things when the names don't match before  
posting. Pairing the names with the dtype is pretty neat, that would  
be quite easy to implement

Go for it. I'm only notified when a ticket is assigned to me directly.
