it would be much easier with vanilla, since these are vanilla features.  
and that would also test part of your new guide, anyway. I think there is  
a page for compilling vanilla somewhere, will search for it later.

although the element being changed belongs to the array defined in another  
struct...
and what will make sense when you have an array made of other arrays?  
doesn't happen very often, but I do have an example in my data-s workshop.
