Hey,
Don't think there is any mentionable overhead in doing that.
___
// WithAttrs returns a new [TextHandler] whose attributes consists
// of h's attributes followed by attrs.
func (h *TextHandler) WithAttrs(attrs []Attr) Handler {
return &TextHandler{commonHandler: h.commonHandler.withAttrs(attrs)}
}
____
It creates a new handler object (shallow copies) but so do also many other
methods.
