Hi Sharing my ignorance: I didn't realise that although you can switch-case on an interface, an array of interfaces doesn't work. https://play.golang.org/p/tD8msjCXyuZ
Any ideas on how to cope with this? I tried: _, ok = tmp.([]Useable) But that fails for the same reason. I can't work out how to detect if the type (of the empty interface) is an array of a type that satisfies the (useful) interface. This must be a common problem and PEBKAC surely?
