C++ trick I pulled today. Like an explicit constructor but context dependent. Any alternatives from folks who’ve needed to do similar? One thing I still need to dig into a little deeper is how copy elision behaves here.

For the array type it can be useful to allow implicit copy to different arithmetic types (design choice, I’m now back to explicit constructors to disallow this for what it’s worth). If allowed though, I still wanted a compile time check like this to ensure that it wasn’t happening by accident in particular circumstances.
