Associating enums with strings in C#
... you'd instead have to have void DoSomething(string groupType), which then means that groupType could have any string value whatsoever, even values that you aren't expecting, which means you have to be prepared for those invalid types and decide how to handle them (e.g. by throwing an exception).

Is there a function to make a copy of a PHP array to another?
...arrays are assigned by copy, while objects are assigned by reference. This means that:
$a = array();
$b = $a;
$b['foo'] = 42;

$a = new StdClass();
$b = $a;
$b->foo = 42;

Python List vs. Array - when to use?
... @Moe, as I pointed out in my answer above, Python's built-in array is not meant for doing math. If you try NumPy's ndarray for summing an array of 10^8 numbers, it will completely blow list away. @tzot has the right idea about why the built-in array is slow for math.
