Research direction

Review responder.go around line 98 and the render.JSON() error path first. Determine whether direct encoding errors can expose internal details, then define and validate a safer behavior or API change; done when the information-leak concern is resolved.

Description

Hi, the JSON rendering code seems to expose direct encoding errors to outside
https://github.com/go-chi/render/blob/master/responder.go#L98

	if err := enc.Encode(v); err != nil {
		http.Error(w, err.Error(), http.StatusInternalServerError)
		return
	}

would it be better to add another function argument to render.JSON() or something, rather than exposing library error messages?
