[antlr-interest] template generation for dumb rules

[Grzegorz Cieslewski]

I am in the similar situation.  In my grammar I have about 100 rules
like that.  I have saved some time by defining all templates in
separate file and creating template  simple(a)::="<a>" and then
invoking it multiple times whenever I have a "dumb" rule.  If any one
knows a better way of doing this I am all ears.
