I agree. Numarray is already confusing enough without identically 
named functions and methods that do different things. (nElements and 
size are another pet peeve, with size used in several places and 
nElements appearing exactly once. Though I am grateful to whoever 
added size as a workalike for nElements; formerly you had to know 
what kind of array you had before you knew how to find out how many 
elements it had.)
