Is it possible to modify variable in python that is in outer, but not global, scope?
...ld a temporary scope. It's like the mutable but a bit prettier.
def outer_fn():
class FnScope:
b = 5
c = 6
def inner_fn():
FnScope.b += 1
FnScope.c += FnScope.b
inner_fn()
inner_fn()
inner_fn()

How to read from standard input in the console?
...lock
reader := bufio.NewReader(os.Stdin)
fmt.Print("Enter text: ")
text, _ := reader.ReadString('\n')
fmt.Println(text)

Is it possible to make anonymous inner classes in Java static?

Using arrays or std::vectors in C++, what's the performance gap?
...roblem you have to keep track of the size, and you need to delete them manually and do all sort of housekeeping.
Using arrays on the stack is also discouraged because you don't have range checking, and passing the array around will lose any information about its size (array to pointer conversion)....
Purge Kafka Topic
