when interpretering sql 

got,

{code:java}
java.lang.AssertionError: interpreter: no implementation for class org.apache.calcite.rel.core.Collect

	at org.apache.calcite.interpreter.Interpreter$CompilerImpl.visit(Interpreter.java:460)

Reproduce this with test case 

{code:java}
@Test public void testInterpretMultiset() throws Exception {
    final String sql = "select multiset['a', 'b', 'c']";
    SqlNode parse = planner.parse(sql);
    SqlNode validate = planner.validate(parse);
    RelNode convert = planner.rel(validate).project();

    final Interpreter interpreter = new Interpreter(dataContext, convert);
    assertRows(interpreter, "[[a, b, c]]");
  }
{code}
