That sounds like a good idea! I didn't see any real good examples of usage
after some googling. Giving more examples of effective usage could also clear
more things up regarding design decisions. Additionally I'm always interested
in learning some new tricks :)
Cheers,

Via my (admittedly infrequent use of) numpy.linalg
http://docs.scipy.org/doc/numpy/reference/routines.linalg.html#linear-algebra-on-several-matrices-at-once
I think it behaves more in line with algebraic thinkers.
I do not have any issue with broadcasting, and use it frequently, but
I've always wanted to see more examples and discussion directly in
the docs, in general.
I have over years post/argued for a doc site more like PHP-doc, where
users can contribute examples and discuss them. There is a wealth of
such examples here in the list and the tutorial, but requires
unnecessary time and Google-foo.
