Yes. For the built in arrays, you would need either templates, or do as 
phobos does internally, work with void * and TypeInfo.

The construct in itself is template less. But if you make your own 
generic container, you will of course need to make your iterator generic 
too.

The "best of all"-part was a joke. :)
