I'm sure keeping the code dry and clean is very good idea, but using 
typeof is rather verbose and just is unusual and verbose a little bit.

Something like this:

alias Tuple!(
     typeof(request_id),
     typeof(zoom),
     typeof(x),
     typeof(y),
     typeof(path),
     typeof(url)
) TileDescription;

// wait for tile descripton to process
auto msg = receiveOnly!TileDescription();

? I didn't understand about trailing []
