[antlr-interest] Same symbols, but two parsed terms

[Сергій Карпенко]

Hi, all.    
    
For example, we have an expression  "--".   It must be parsed as NOT '-'-symbol.    
    
And we have a gramar:    
    
  expr : NOT? WORD+;    
  NOT : '-';    
  WORD: '-'+;    
    
input string is "--"    
    
result is "--" term.    
    
Warious combinations of parenthesis didnt help.    
    
Thanks.
