Unfortunately, when you loop this way you can't tell which iteration of the loop you are on without incrementing a separate variable within the code. Granted, you don't always need to know which iteration you are on, but it's ugly when you do.

Looping over a collection, be it list, struct, array or otherwise should all conform to a standard syntax.

I find myself often wrapping collections up in my own iterator objects so if I switch the implementation of a collection from array to struct looping over the collection can still be done with the same syntax.

For example:

for( var item in array ) {
doSomething(item);
}

instead of:

var item = “”;
for( item in array ) {
doSomething(item);
}
