Vladimir Sitnikov commented on CALCITE-2416:
--------------------------------------------
[~ipatina], the PR looks good to me, however could you please just replace
existing {{throw new AssertionError}} with {{throw new
IllegalArgumentException}} in {{org.apache.calcite.sql.SqlLiteral#unchain}} ?
I don't think {{node instanceof SqlCall}} is required there. A generic
{{IllegalArgumentException("not a literal: " + node);}} is enough.
