Hi List,
Is it possible to define how 'in' works for an object of a specific class
(to achieve a similar result to implementing the iterator protocol in a
class Python)?
Cheers,

Would you allow a list argument to diag() as well? I see that
Matrix::Diagonal does not accept it. Perhaps nothing in Matrix deals
with matrices of lists, but they are handy and for diag() it may be
simpler to allow lists than to check for and reject them.

Not unlikely. (I goofed and thought that it only affected the development
version.)

No, Peter, I have the "(2014-07-10, Sock it to Me) R-3.1.1.tar.gz" source.
Thanks for pointing it. So (I hope) it should be ok. Right?
