Is it possible to forward-declare a function in Python?
...st, but it's clean.
You could create a recursion like the following:
def foo():
bar()
def bar():
foo()
Python's functions are anonymous just like values are anonymous, yet they can be bound to a name.
In the above code, foo() does not call a function with the name foo, it calls a funct...
What's the difference between using “let” and “var”?
...sing block denoted by { } (hence the block scope).
function run() {
var foo = "Foo";
let bar = "Bar";
console.log(foo, bar);
{
let baz = "Bazz";
console.log(baz);
}
console.log(baz); // ReferenceError
}

The reason why let keyword was introduced to the language was f...
What is the difference between self::$bar and static::$bar in PHP?
...eferring to the class within which you use the keyword. In this case, your Foo class defines a protected static property called $bar. When you use self in the Foo class to refer to the property, you're referencing the same class.
Therefore if you tried to use self::$bar elsewhere in your Foo class ...

Why does the Scala compiler disallow overloaded methods with default arguments?
...guate overloaded versions) into the naming schema, e.g. in this case:
def foo(a: String)(b: Int = 42) = a + b
def foo(a: Int) (b: Int = 42) = a + b
it would be something like:
def foo$String$default$2 = 42
def foo$Int$default$2 = 42

Can I implement an autonomous `self` member type in C++?

Here's how you can do it without repeating the type of Foo:
template <typename...Ts>
class Self;
template <typename X, typename...Ts>
class Self<X,Ts...> : public Ts...
{
protected:
typedef X self;
};
#define WITH_SELF(X) X : public Self<X>

Decorators with parameters?
...s.
One way of thinking about decorators with arguments is
@decorator
def foo(*args, **kwargs):
pass
translates to
foo = decorator(foo)
So if the decorator had arguments,
@decorator_with_args(arg)
def foo(*args, **kwargs):
pass
translates to
foo = decorator_with_args(arg)(foo)

What's the _ underscore representative of in Swift References?
...by default don't have external parameter names.
For example, we have this foo() method defined in class Bar:
class Bar{
func foo(s1: String, s2: String) -> String {
return s1 + s2;
}
}
When you call foo(), it is called like bar.foo("Hello", s2: "World").
But, you can override...
