[antlr-interest] Operator tree construction in rewrite syntax

[Thomas Brandon]

I think you can do something like (syntax not checked):
sum: s1=something -> $s1 (Plus s2=something -> ^(Plus $sum $s2) )*;
I'm not sure if you need the first rewrite or whether it will already
have it when you use $sum (the previously constructed tree for the
rule).
