Check for nil and nil interface in Go

Question

Currently I\'m using this helper function to check for nil and nil interfaces

func isNil(a interface{}) bool {
  defer func() { recover() }()
  return a == n

If neither of the earlier options works for you, the best I could came up so far is:

if c == nil || (reflect.ValueOf(c).Kind() == reflect.Ptr && reflect.ValueOf(c).IsNil())

At least it detects (*T)(nil) cases.
