Is this such a sample (untested):


function Array()
{
     var r = [].constructor.apply(Array.arguments);
     for(var i in r)if(typeof r[i] == 'string') r[i] = r[i].toLowerCase();
     return r;
}
a = new Array('A','B');
alert('lower case now...\n\na[0]: '+a[0]+'\na[1]: '+a[1]);



and the more complex standard like implementation (tested):


var A = Array;
Array = function()
{
     var r = Array.$__Array.apply(this, Array.arguments);
     for(var i in r)if(typeof r[i] == 'string') r[i] = r[i].toLowerCase();
     Array = Array.$__Array;
     return r;
}
Array.$__Array = A;
a = new Array('A','B');
alert('lower case now...\n\na[0]: '+a[0]+'\na[1]: '+a[1]);
