Notwithstanding this legacy, a progressive approach might include two additional new commands, lhs(), and rhs(), to make both the ppl, and CAS more useful, and more consistent with their more robust, but comparable products. I'm not sure you realize that, but what you ask is a little bit like asking + to work in RPN mode like in algebraic mode, after all writing 2+3 is more intuitive than << 2 3 + >> or '2+3' EVAL. Evaluation is at the heart of how a CAS work, you can not change that. Matlab is not a CAS, you can't compare. Maple is a CAS and looking at Han's explanations it does (almost) the same as Giac. Maxima is also a CAS but it does not really handle inequations, for example you can't solve(y^2>2,y), therefore it's easier for Maxima to keep > >= < <= inert.
