Peter,

It's really heavily influenced by the parser being used, with a handcoded
LL(1) parser you can include all sorts of fancy error processing and recovery,


The parser being used influences the technical problems of
getting thing to work well.

I have seen bad error recover with LL and very good error
recover with LALR.  It's just a case of investing enough effort (and
knowing a bit about how to do it :-).
