[Swift-devel] Problem with iterate

I think doing it statically (i.e. at compile time) is equivalent to 
executing the code (including external apps) - I think there's probably a 
straightforward example where something depends on an integer read from an 
externally executed app which then influences an if statement that decides 
which of two different arrays is being written to; or something like that.

But I think it could be done at runtime (which is less pleasing, but still 
better than a runtime hang).
