Javascript Recursive AppendChild Function

I am coding an AJAX DHTML whatever application and I was fed up with
always typing a lot of appendChild() functions.

I created a custom one called append_children() and wanted to share it
if anyone need such a function.

function append_children() {
var a = append_children.arguments;
for ( var i = a.length - 1; i > 0 ; i-- ) {
try {
a[i-1].appendChild(a[i]);
} catch(e) {
for ( var j = 0; j < a[i].length; j++ ) {
append_children(a[i-1], a[i][j]);
}}}}
