This one's a bit complicated. If array() is passed a list of lists,
there are two different orders that are relevant - the output order of
the array, and the order used to interpret the input. I suppose that
if L is a lost of lists, array(L)[2,3]==L[2][3], that is, in some
sense the arrays are always logically C-ordered even if the underlying
representation is different. Does it make sense to specify this
somewhere in the docstring? At least it would be good to make it clear
that the order parameter affects only the underlying storage format,
and not the indexing of the array.
