ExtJs namespace alias

Is there any way to give a namespace an alias?

ergo i want to do

Ext.ns ( 'somereallylongname' );

and then alias it to 'srln' and be able to do

Ext.ns ( 'srln.panel');

and create it by

Ext.create('somereallylongname.panel');

Example is a bit contrived, but meh.

Try

Ext.ns ( 'somereallylongname' );
var srln = somereallylongname;

added

make sure srln is in global scope
