Python (and Python C API): __new__ versus __init__
...behavior of __new__. We pass cls explicitly to __new__ because, as you can read here __new__ always requires a type as its first argument. It then returns an instance of that type. So we aren't returning an instance of the superclass -- we're returning an instance of cls. In this case, it's just the...
Why are Perl 5's function prototypes bad?
...lt-ins, all of which know what to expect from the succeeding code. You can read about prototypes in perlsub

How does the Java 'for each' loop work?
...va.util.Iterator--it's syntactic sugar for the same thing. Therefore, when reading each element, one by one and in order, a foreach should always be chosen over an iterator, as it is more convenient and concise.
foreach
for(int i : intList) {
System.out.println("An element in the list: " + i);
