      When a $match has an expression that, when compiled, leads to an empty filter, we don't check if the caller is able to process block values

       db.repro.explain().aggregate([{$project: {"obj.obj": 1}}, {$match: {$or: [{"hidden": {$bitsAnySet: NumberInt(6)}}, {$expr: {$literal: true}}]}}, {$sort: {_id: 1}},  {$group: {_id: null}}])
