The new chapter on Vectorization has been committed to Mercurial so this bug is no longer a blocker for the 3.6.0 release.

I've run into a bit of a problem... how should the in-place operators
be handled? += .*=, etc....

I was thinking that they shouldn't resize the LHS, because that
wouldn't be in-place anymore (without allocating more memory, I mean).
But jwe thinks that this would break semantics with x op= y being
purely syntactic sugar for x = x op y.

How should this case be handled? I had opted earlier for no resizing
of the LHS, but I didn't do it correctly, and jwe thinks this isn't
completely the right idea. Should I undo my previous changes that
disallowed resizing the LHS in x += y ?

This is completely an Octave-specific issue, because as you know,
Matlab doesn't even have op= operators.

Do you have a target date for this update?

It would be nice to have a chance to review
the text before 3.6 release.

The new broadcasting rules for binary operators need very careful documentation and Octave 3.6 shouldn't release without it. I'm already working on this and should have it ready within a few weeks in time for the release.
