====== Expression Operators ======

PPL allows the following operators to be used in expressions (lvalue and rvalue are simply the values to the left and right, respectively, of binary operators):

      (  - Start sub-expression (also allows [ to be used)
      )  - End sub-expression (also allows ] to be used)
      ^  - Raise lvalue to the power of rvalue (also allows ** to be used)
      *  - Multiply lvalue by rvalue
      /  - Divide lvalue by rvalue
      %  - Remainder of lvalue divided by rvalue
      +  - Add rvalue to lvalue
      -  - Subtract rvalue from lvalue
      =  - Is lvalue equal to rvalue (also allows ==)
      <> - Is lvalue not equal to rvalue (also allows != and ><)
      <  - Is lvalue less than rvalue
      <= - Is lvalue less than or equal to rvalue (also allows =<)
      >  - Is lvalue greater than rvalue
      >= - Is lvalue greater than or equal to rvalue (also allows =>)
      !  - Logical not of rvalue
      &  - Logical and of lvalue with rvalue (also allows &&)
      |  - Logical or of lvalue with rvalue (also allows ||)
