I vote for 3) too.  

Especially annoying is when I mistakenly type a.shape instead of a.shape()
interactively.  Without the parentheses I get a bound method, the repr of
which includes the repr for the whole array, and when this has > 25
million elements it really is a drag to wait for it all to finish spewing
out...

Getting sidetracked... is this repr of methods a feature?

>>> l = [1,2,3,4]
>>> l.sort
<built-in method sort of list object at 0x402d4eec>
>>> a = numarray.array(l)
>>> a.shape
<bound method NumArray.shape of array([1, 2, 3, 4])>

It would seem more pythonic to get 
<bound method NumArray.shape of array object at 0x402d4bcc>
or similar?
