[Swift-devel] Re: arrays of structures and building them in SWIFT

[Mihael Hategan]

Right. The problem here is that you can't reasonably "assign" file names
to data on the fly.

How do your files look like? In other words, what are your input files?
(I get the ones in the graph, but you mention an array, so I figured
there's more).
