// Wrap is a simple wrapper around Errorf that is doing error wrapping. You can read how that works in
// https://godoc.org/golang.org/x/xerrors#Errorf but its API is very implicit which is a reason for this wrapper.
// There is also a discussion (https://github.com/golang/go/issues/29934) where many comments make arguments for such
// wrapper so hopefully it will be added in the standard lib later.
