Now that you mention it, many of my concerns are addressed by having 
access to the code generators.  I think there is a middle ground 
between the raw grammar handling and the action code.  That space is 
where things like tracing, tree node construction and exception 
handling strategies should be implemented.  These are the things that 
affect all the generated code, but which shouldn't have to be specified 
in each action.

Some way to isolate these global user specified behaviors from strictly 
grammar based code gen would be handy.  That's my goal for an 
aspect-oriented approach to ANTLR--simple, clear specification of that 
code which pervades all the actions.  It's like having control of the 
environment in which actions take place.

Really I'll just have to start hacking the code generator and see what 
falls in place.
