D could certainly add a few more helper functions to work on 
multidimensional data or perhaps an article, I admit I was 
unaware joiner could be chained without mapping like that. One 
that regularly irritates me is arrays of results that you want to 
make eager such that you can map a lazy function to a 2D array 
and then store the result in a 2D array again. This seems messy 
and I'd like a function that will take absolutely anything and 
force eager assessment.

auto a = res.map!array.array; // De-lazying 2D result

Would like:

auto a = res.eager;
