> In core/src/main/java/org/apache/calcite/sql/fun/SqlItemOperator.java, the
> behavior and the documented signatures for VARIANT are inconsistent between
> getAllowedSignatures and getChecker:
> * getAllowedSignatures declares the following signature for ITEM:
> ** <VARIANT>[<ANY>]
> * However, getChecker currently returns:
> **
> OperandTypes.family(SqlTypeFamily.INTEGER).or(OperandTypes.family(SqlTypeFamily.CHARACTER))
> for VARIANT , effectively allowing only integer or character indexes.
