in a nice D-style range interface.
Do I have to allocate a new D array and copy the `AVStream*`
elements into that or is there a convenience wrapper for
constructing a lazy range from a C style Array-pointer plus
array-length?
Note that the elements of the C array are pointers to structs,
in this case instances of `AVStream`. This, of course,
complicates the matter with regard to GC-safety.
Comments on that please :)
I think a wrapper is quite easy to do, isn't it?
You just need to implement front popFront and empty and you're
done.
So you avoid slice-related problems...
