Cool, GLL is the way to go IMO, but I am also looking at 
Earley-parsers. What is the advantage of GLL over Earley if you 
use a parser generator? I think they both are O(3) or something 
like that?

I think D is close to LL(2) for the most part. But I suppose a 
GLL parser could allow keywords to be used as symbol names in 
most cases? That would be nice.
