Thanks for your reply.

The reader macro is for executing foreign functions. I am reasonably sure t=
hat it only reads the word following it, which is the name of the C++ metho=
d to be called. Overloading +=3D in C++ is done by overloading the function=
 named operator+=3D. So I assumed it would be the same in commonqt.

It appears that there is a function #_operator, and the +=3D is being evalu=
ated normally as the first argument and of course it is unbound. I have to =
figure out how to use it. There is no documentation which I can find on #_o=
perator.
