Just to expand on Ian's reply: you seem to want to have loadPage return any
errors, similar to what ReaedFile does. If so, you need to declare loadPage
to return two values, like so:
func loadPage(title string) (*Page, error)
And return a nil *Page and the error if ReadFile fails:
body, err := ioutil.ReadFile(filename)
if err != nil {
return nil, err
}
The same goes for the sucess path:
return &Page{Title: title, Body: body}, nil
