   The lookahead example of ++ vs += isn't very good since a LALR   
   parser only needs to look ahead when it reduces but in general you're   
   right, it'd be a problem.  A much worse problem in combined parsers is   
   getting rid of noise like comments and white space.  In a separate lexer   
   you can easily discard them between tokens, in a combined lex/parse you   
   have to include them everywhere they can occur. -John]
