i tried methods in base for Dequeues, but it seems some of them are not implemented for DataArray. For example:
a=@data([NA,3,5,7,NA,3,7]) b=copy(a[2:end]) append!(b,[NA]) append! works, but prepend! gives no methods error. also deleteat! works but insert! no methods. anyway, other methods works well.
