... loop can be inlined without any impact on the code size.
For example, on my system the following code takes around 70% of the run time if the anonymous namespace is used (x86-64 gcc-4.6.3 and -O2; note that the extra code in add_val makes the compiler not want to include it twice).

...'s a more concrete example why non-numeric keys don't "fit" an Array:
var myArray = Array();
myArray['A'] = "Athens";
myArray['B'] = "Berlin";
alert(myArray.length);
This won't display '2', but '0' - effectively, no elements have been added to the array, just some new properties added to the arr...
