      If I try to index two fields that are arrays without the presence of a 2dsphere index, when I try to insert a document, I predictably get the errmsg "insertDocument :: caused by :: 10088 cannot index parallel arrays [field1] [field2]".

      If I create the index with a 2dsphere in it, it allows such insertions, and it appears that it even uses the index in the query plan!
