I think the indexing with callables is more syntax sugar for nested
`func(v, axis=n)` than anything else. It may be more useful interactive
use than calling the functions, though. Compare:
mean(sum(x, axis=1), axis=1)
It might be useful also for broadcasting functions operating on 1D
vectors to the whole array, but here the semantics start getting muddier.
These, apart from zcen, were just some demo functions I pulled out from
The actual list of Yorick functions relevant here appears to be here:
I must say that I don't see many functions missing in Numpy...
David (Strozzi): are these the functions you meant? Are there more?
