this enables a syntax for constructing key-value pairs with values that can be written to a DBObject -
i.e. because the value type has a EncodeBsonField instance
"string" :> <some encodable>
also, you can get an Option of a DBOKV:
"string" :> Some(<encodable>) //gives you Some(DBOKV("string", ))"string" :> None//gives you None
