I'm sure you know better, but at first glance this seems wrong. Reason: `main` is not itself a template, so `cast` is not a dependent name.

You're right, since I'm frequently using templated functions I encounter this issue quite often, but here when I wanted to give an example I forgot I needed to be in a dependent context. I guess I'd better test my example next time I want to give one...
