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
