   Hi,   
      
   I am exploring the possibility of choosing between several lexers depending   
   on the current state of an LALR parser (i.e. if a state can accept   
   productions such as A => A . 'a' b, B => . 'c', then the selected lexer will   
   accept (at least) 'a' and 'c', for rightmost positions the lookahead symbols   
   would be acceptable as well)   
      
   Is there any literature about this? or example? I searched around for   
   scannerless/lexerless parsing but could not make my mind.   
      
   Regards
