[antlr-interest] multiple command queues to get multiple rewrites from a single pass

[Michael Scholz]

Referring to The Definitive ANTLR Reference, page 220

"You can also have multiple command queues to get multiple rewrites from a
single pass over the input such as generating both a C file and its header
file (see the TokenRewriteStream Javadoc for an example)"

said example:
/*  You can also have multiple "instruction streams" and get multiple
 *  rewrites from a single pass over the input.  Just name the instruction
 *  streams and use that name again when printing the buffer.  This could be
 *  useful for generating a C file and also its header file--all from the
 *  same buffer:
 *
 *      tokens.insertAfter("pass1", t, "text to put after t");}
 *         tokens.insertAfter("pass2", u, "text after u");}
 *         System.out.println(tokens.toString("pass1"));
 *         System.out.println(tokens.toString("pass2"));
 *
 *  If you don't use named rewrite streams, a "default" stream is used as
 *  the first example shows.
 */

I don't see how to apply this in the context of the CMinus.g 1pass rewriter.
This example uses inline template definitions to rewrite, and the syntax for
doing that:
... -> template-name(<<attribute-assignment-list>>)
doesn't have any obvious way to specify the non-default instruction
stream... to generate a replace(String,...) instead of replace(...) in the
parser file.

If this functionality is enabled, the documentation for getting to it is not
obvious. Is this a V2/V3 issue? The tweak example seems like it might be
closer than 1pass rewriter, but it doesn't look consistent with the book's
techniques.
