Including the name of a rule in an action

[Tom Stellard]

I am currently using: yytname[yyr1[yyn]] to access the name of the
rule that each action is associated with.  For example:

program:        classes { printf("rule: %s\n",yytname[yyr1[yyn]]);}
                ;

Is this the recommended way to do this, or is there a better way?
Thanks.
