[antlr-interest] linear list from tree

[marc schellens]

I would like to build a linear list made from the 'expr'
in the following grammer fragment.
This way it does not work.
So how to do it?

Thanks,
marc


arrayindex_list!
	: ( #(ARRAYIX
                 ( ALL
                 | ( e1:expr // 0 or 2
                         {
                             #arrayindex_list = #( NULL, (arrayindex_list),e1);
// also not working:        #arrayindex_list = #( arrayindex_list,e1);
//                          #arrayindex_list = #( (arrayindex_list),e1);


                         }
                     )
                 )
         )+
         {
//            #arrayindex_list = #([ARRAYIX,"[...]"], arrayindex_list);
//            #arrayindex_list->SetArrayIndexList( ixList.release());
         }
	;
