Comment on attachment 298520 [details] possible alternate approach Clear r? to reflect the fact that I still need to add unit tests, and doing so will probably unearth bugs in how I wrote my enable_if constraints.

I like both of these. I normally judge such things by how good they look at call sites, how good the error messages are when you use them wrong, whether there are any cases where they do something surprising when you use them wrong, and how portable the technique is. I don’t have a preference between the two approaches in this bug given these criteria, so I would be tempted to use the more straightforward approach until things got complex enough that the traits solution really started to pay off.
