proof of concept code -- version 3

The bug is not specific to binary/unary operators 
BUT RATHER 
the combination of an elemental operator where one argument is an array and the
other argument a scalar result of another operator.

The current code example (poc version 3) shows the bug using 

<array> = <array> .<binary elemental operator>. (.<unary operator>. <scalar>)
OR
<array> = <array> .<binary elemental operator>. (<scalar> .<binary operator>.
<scalar>)
