overload arithmetic assignment operators?

[Steve White]

Hi,

I gather from
    http://www.gnu.org/software/octave/doc/interpreter/Assignment-Ops.html
and
    http://www.gnu.org/software/octave/doc/interpreter/Operator-Overloading.html
that there is no way in octave to directly overload arithmetic assignment 
operators (+=, *=, etc.); 
evidently the assignment operators are based on the binary arithmetic ones.

This is really a pity, efficiency-wise, for classes that might use these 
operators.
The binary operators typically require the constructon of a new class object,
while assignment operators don't.  If efficiency were important, then the binary
operators should by default be defined in terms of the arithmetic assignment 
operators.

What do you think?

Is it worth a wish?
