I think you will find a lot of people who also have thought in similar 
ways here on this mailing list.  I for one would like to see an operator 
that allows us to distinguish between element-wise and object-wise 
operations.  In the end, though, it hasn't been enough of a "need" for 
me to put in the considerable time and energy needed to convince others 
who use Python that the additional complexity is worth the added benefit. 

What it really takes to get something changed in Python is:

1) a champion willing to write a PEP, shepherd it through many revisions 
and critiques and eventually write the implementation.  As somebody who 
has both published in peer-reviewed journals and written two PEPs, 
publishing a paper is easier to do.

2) the ears/eyes of Guido or one of his trusted developers.  Note that 
these resources are not too difficult to obtain once #1 is accomplished...

So, your criticisms and concerns are valid and useful.   Perhaps someday 
we can make a case sufficient to make a change regarding the operator
