With regard to patch 4, how much thought have you and Hernan given to 
backward compatibility?  Once herd7 is changed, old memory model files 
will no longer work correctly.

To avoid being so disruptive, perhaps the changes to herd7 should be 
under control of a new command-line or config-file switch.  If the 
switch is enabled, the new simplified code gets used; otherwise herd7 
would continue to use its old built-in rules for special tags.
