One way of interpreting the requirement is to have other operators in
the assign statement e.g:

assign(j+=3)
{

}

Another way would be to have REAL variables e.g:

module main()
{
       j=3;
       echo(j);
       j=4;
       echo(j);
}

I would have expected the above script to output:
ECHO: 3
ECHO: 4

Currently the output is
ECHO: 4
ECHO: 4

That seems pretty confusing to me, and apparently to others.
Finally there would be a full compliment of operators that could be
used to change those variables.
