// At this example you will see how to convert any net/http middleware
// that has the form of `(HandlerFunc) HandlerFunc`.
// If the `raven.RecoveryHandler` had the form of
// `(http.HandlerFunc)` or `(http.HandlerFunc, next http.HandlerFunc)`
// you could just use the `irisMiddleware := iris.FromStd(nativeHandler)`
// but it doesn't, however as you already know Iris can work with net/http directly
// because of the `ctx.ResponseWriter()` and `ctx.Request()` are the original
// http.ResponseWriter and *http.Request.
// (this one is a big advantage, as a result you can use Iris for ever :)).
//
// The source code of the native middleware does not change at all.
// https://github.com/getsentry/raven-go/blob/379f8d0a68ca237cf8893a1cdfd4f574125e2c51/http.go#L70
// The only addition is the Line 18 and Line 39 (instead of handler(w,r))
// and you have a new iris middleware ready to use!
