This won't work (arrays may contain null/0 entries), and it would be
slow.

This would at least break memory management, and it looks like a strange
combination of C and Vala syntax, not easy to understand.

Might work if we treated the element method specially, doesn't sound
that straight forward to me.

We don't want free functions in the bindings API, we already have
`delete' to free memory if you use raw pointers.
