I wasn't saying it was hard. "Major" is an orthogonal dimension.

That doesn't prevent replacing it (and the various constant-generating
parts of the generator proper) from being a relatively major change to
the parser generator.

Henning Makholm             "Han råber og skriger, vakler ud på kørebanen og
                          ind på fortorvet igen, hæver knytnæven mod en bil,
                     hilser overmådigt venligt på en mor med barn, bryder ud
                    i sang og stiller sig til sidst op og pisser i en port."
