Thanks for your suggestion. It's not as attractive though, it 
would be the same as v.arr[] = ..., exposing the naked array. The 
syntax also becomes a bit confusing.

With alias this it works, but functionality is lost. See

It feels not consistent, so I guess that's the reason for the 
"not implemented" message.
