Right now, to get an acceptable experience in dtlv, one has to use rlwrap, i.e. launch it like this rlwrap dtlv. It would be nice to integrate with jline3 library to have a better experience natively.

Hi, all. Currently, clover allows to access nested document fields by the following syntax:

doc.Get("field1.field2.field3")

Now, suppose that field2 is a slice. It would be useful to support indexing elements by the following syntax:

doc.Get("field1.field2.4.field3") // here, we are trying to access the fifth element of "field2"
