I have written a lexer and parser for a programming language syntax
using flex and byacc that produces abstract syntax trees. I would
like to be able to save the beginning and ending source code location
of each piece of concrete syntax inside the abstract syntax node that
represents the syntax form.


I am aware that I could add an action that is executed before a
particular form is recognized that saves off the source location, but
I am hoping for a solution that leaves my grammar in a nicer
condition.
