get rid of unary '-' operator

the unary '-' is a very odd case in the report and causes a lot of confusion.

to fix it we can

  • make - part of the lexical syntax of numbers. so a - followed by digits is interpreted as a negative number
  • get rid of all other special treatment of -
  • people can use 'negate' if they want to negate non literals.
