Even though I made a mistake about the parentheses. My BNF reading 
was correct. I did cut the BNF definitions to valid statements and 
opions only. So, you need to reread my post. 

I said:

Ada LRM 4.4 ( 7 ) =>   primary ::= numeric_literal | .. | (expression)

  +Right  => is defined as an expression
  -7      => is defined as an expression

-- ---------------------------- --
-- For other statements see other post --
-- ---------------------------- --

Ada LRM 4.4 ( 7 ) =>   primary ::= numeric_literal | string_literal 

  Right  => string_literal 
  7      => numeric_literal


So, where did I claim that "+Right" was a numeric literal?  I do not 
see that.  I define the "+Right" as an expression and then later 
define "Right" as a string_literal.  which is correct except that the
expression definition requires parentheses.
