> org.apache.calcite.adapter.enumerable.RexToLixTranslator#translateLiteral creates ConstantExpression with {{List}} contents, and  org.apache.calcite.linq4j.tree.ConstantExpression#write just misses a case for List/Map, thus it resorts to plain {{toString}} and produces the following code:
> {code:java}
>             public Object current() {
>               final org.eclipse.mat.snapshot.model.IObject v0 = com.github.vlsi.mat.calcite.functions.ISnapshotMethods.getIObject(com.github.vlsi.mat.calcite.SnapshotHo

>                   [0, 1], <-- does not compile
