In Freemarker - how do I get the first value in a map

in Java I would do something like this:

map.v开发者_JAVA百科alues().iterator().next();

How do you do it in Freemarker? something like this?

${map?values?first()}

---

${map?values[0]}

Or if you are not sure that the map is not empty:

${map?values[0]!someDefault}
