I disagree. If their internal parser is never published, then neither
of us can say exactly what their code does. I believe that even if I
never use the back-bar-square-brackets that their parser will still
save previous values. It is the easiest thing for their programmers
to do; do the same thing in all situations. However, if I supply
the output value from one function as the input value to the next
function, then there is no intermediate variable that gets assigned.

The need for this is to have explicite and total control over their
parser and to not let their assumptions dictate how my code performs.

Until their parser specifications are published, then this statement
cannot be proven.
