> Consider the following example :
> 		String jexlExp = "$$__INPUT + nl";
> 		Expression e = jexl.createExpression( jexlExp );
> 		// Create a context and add data
> 		JexlContext jc = new MapContext();
> 		jc.set("$$__INPUT", "\r" );
> 		jc.set("nl", "\n");
> 		// Now evaluate the expression, getting the result
> 		Object o = e.evaluate(jc);
> The result is 0 instead of "\r\n"
