This sounds nice! Does this mean that it would be possible to use 
your parser generator to create a skeleton which is then 
manipulated manually or is there non-local complexities that 
makes manual edits risky?

One reason I believe GLL is the right way to go is that I think 
RD makes it easier to generate good error messages suitable for 
display (to the end user).
