good use case for this would be code produced by lightningcss in vite 8 for css modules:

var MyStyle_module_default = {
	main: "_main_ahlzm_2",
	placeholder: "_placeholder_ahlzm_31",
	content: "_content_ahlzm_36",
	item: "_item_ahlzm_54"
};
//....
	{
		className: MyStyle_module_default.main,
	}
//....

playground

var Button_module_default = {
	"primary": "_button_tertiary_stejx_2",
	"secondary": "_button_tertiary_stejx_3",
	"tertiary": "_button_tertiary_stejx_8"
}, variants = {
	primary: Button_module_default["primary"],
	secondary: Button_module_default["secondary"],
	tertiary: Button_module_default["tertiary"]
}
