Things go fast and sometimes unnoticed. I try to follow the news, but only now did I see this : E4X !
var x = <people> <person gender="male"> <name>Ant</name> <hair>Shaggy</hair> <eyes>Blue</eyes> <height measure="metric">176</height> </people>; print(x.person.name);
It is a revolution in the code, for thoses who had to write
var peopleElem = doc.createElement("people"); root.appendChild(peopleElem ); ... !
