how to get enum value internal name in javascript template

this has ben bugging me a lot lately. When using an enum in for instance the recipient table in a template you get the label of the enum value, but for programmatic reasons I want to access the (acually stored) internal name of the value, and not the "translation". I thougt it was some .toString() or similar to get it but I can not find any documentation or way around other that loading the whole enumeration and translating it back...
