// Unfortunately, C# (at least up to version 6) does not support enum type constraints. There's
// ways to work around it in some situations (https://stackoverflow.com/questions/79126/create-generic-method-constraining-t-to-an-enum)
// but not in a way that will allow us to convert an int to the enum type.
