The Default syntax now simpler

I am removing anything tod o with operand ordering, in fact strings with operands are identified and delivered to  shut which returns it in the form needed. I need only handle the looping and provide the symbol interface. The code to consume the unfolded expressions was already written (I figured this out before). Great news, ode deleted always my favorite software task. I can do loops in a few dozens of lines, maybe farm out the symbol table to a probuilt device, just add the interface.

But right now, my net cost of  Default syntax (official language name) , beyond Expr, is dozens of lines plus symbol table. So simple.
