> needs to fire for the (added in 1.35.0) kind SqlKind.SAFE_CAST, or the SAFE_CAST does not work in SQL.
> I could submit a repro if it's not obvious, but it should be as simple as something like `b.scan("emps").project(b.rexBuilder.makeAbstractCast(b.typeFactory.createSqlType(SqlTypeName.INTEGER), b.field(0), true))` and trying to write SQL from that. The second SqlDataTypeSpec argument won't get added, and it will fail the assertion error about two operands in SqlCastFunction.unparse
