->RPN has one argument, a program or an algebraic object, to be replaced by 
its RPN-equivalent, see DEMO. For instance, the RPN-equivalent of the program
<< -> x y `(x^2+y^2)` >> is << -> x y << x 2 ^y 2 ^+ >> >> which is about 5% 
faster than its source. Thus, it pays to replace an algebraics occurring in a 
program by its RPN-equivalent which is easily done with ->RPN. The outermost 
program quotes are unvisible in a ->RPN output. This saves additional space.

The only difference in the compilation of an algebraic and its RPN-equivalent
is that the SysRPL-word SYMBOL is replaced by the SysRPL program start symbol.
Thus, the time delay in executing an algebraics compared with the execution
of its RPN-equivalent is surprising and hardly to explain.
