empty interface{} and struct tags really shine when used as a library author, or authoring a bit of extremely reusable code that’s pervasive throughout a codebase. Think things like json encoding (entirely réflection based), or writing a set of functions that can operate on something more generic. It’s not scary and it’s not really that slow, you just need to be very particular and choosy in your application of it. |
