[antlr-interest] Referencing upper tree node from lower level

You can pass the primaryExpression as an argument to elist:

[...]
| #(METHOD_CALL p:primaryExpression elist[p])
...
;
elist[AST p] 
: #( ELIST (expression
              {
              //do something with p here
              }
           )*
   )
;
