[antlr-interest] Building Treenodes from Kleene Closure

If I have the grammar:


expression_list
    :
expression (EXPRESSION_LIST_SEPARATOR expression)* -> EXPRESSION_LIST
;

Is there anyway to build the AST such that *n *EXPRESSION_LIST_SEPARATOR
nodes actually appear the number of times the separator appears in the
input?  If so, how would I express that on the right hand side of the arrow?
