Pretty true. One advantage of having an accurate error repairing
technique like BF, is that you get really good quality error diagnosis,
and also most of the times you can even diagnosis correctly the
corrections for multiple errors that occur in close proximity.

I'm on the task of putting online my git's clone of bison's repository,
where I implemented BF.
