[Octave-bug-tracker] [bug #38466] incorrect broadcasting for 'a .*= b' when b has fewer dimensions than a

[Jordi Gutiérrez Hermoso]

Follow-up Comment #2, bug #38466 (project octave):

Actually, wait. I remember now. I deliberately did it this way, thinking that
a .*= b shouldn't change a's size, thinking that broadcasting this way should
work in-place without allocating temporaries or more memory. In particular,
since it must be in-place, it can't change size(a).

But jwe thinks that a .*= b should be syntactic sugar for a = a .* b and
shouldn't attempt to do any sort of tricks like this. At the moment, there is
some code, not a lot, that actually attempts to be more efficient with the a
OP= b operations than a = a OP b. What do you think should happen?
