[antlr-interest] Rewrite rules, again!

[Shaun Bogan]

I got some great help creating the following for my grammar:

assignops :
(boolops->boolops)(firstops b2=boolops -> ^(OPERATOR ^(firstops
^(OPERAND $b2) ^(OPERAND $assignops))))*
;

To make the above clear, it is basically just:
assignops :
    boolops (firstops boolops)*
    ;
with rewrite rules.

The problem is this creates an AST that groups items in the reverse of
how I need them.  For example:
a = b = c;
will create a tree that my tree walker (doing depth first) would evaluate as:
(a = b) = c;

This is obviously wrong.  It should be a = (b = c);

Essentially, my parse tree looks fine, but I can't figure out how (if
there is a way) to get my rewrite rule to write my AST like above.

Any help is greatly appreciated,
