proof of concept code -- version 3

The bug is not specific to binary/unary operators=20
BUT RATHER=20
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=20

<array> =3D <array> .<binary elemental operator>. (.<unary operator>. <scal=
ar>)
OR
<array> =3D <array> .<binary elemental operator>. (<scalar> .<binary operat=
or>.
<scalar>)=
