I'd also like to see a way to make the constructors create floating-point arrays 
by default.

(just as an aside, a further possibility is the relative availability of 
documentation for numpy and the other array packages. I entirely understand the 
reasoning behind the Guide to NumPy being a for-money offering but it does 
present a significant barrier to adoption, particularly in an environment where 
the alternatives all offer for-free documentation above and beyond what is 
available in the docstrings).
