It's never right to make it easy for the compiler writer at the expense
of the programmer.  And here there is /no/ cost at all to the compiler
writer.  The compiler must be able to parse '+42', '- + 42', '- -12' and
so on, so you save nothing in the parser logic by adding a special form
of negative literal.
