Functions can be declared inside other functions, and access the outer function's local variables.
2.
Let " G " be an outer function represented as above from a function ? on the circle.
3.
Furthermore, they implement full closures by remembering the outer function's local variables even after the outer function has exited.
4.
Furthermore, they implement full closures by remembering the outer function's local variables even after the outer function has exited.
5.
They need to be heap allocated instead, and their lifetime extend beyond the lifetime of the outer function that declared and allocated them.
6.
Replacing ? by ? ?, ? > 0, a family ( " G " ? ) of outer functions is obtained, with the properties:
7.
If the nested function is returned as a result from its outer function ( or stored in a variable ) the non-local variables will no longer be available on the stack.
8.
If this identifier is not found, it looks in the outer function that declared the local one, and so on along the " scope chain " until it reaches the " global scope " where global variables reside.
9.
In the hangar, the Terminator, unable to control his outer functions but still consciously aware, attacks John and Kate before John convinces it to reject the T-X's control, and deliberately shuts its corrupted system down, enabling John and Kate to escape.
10.
Closures are used to implement continuation-passing style, and in this manner, run-time, when the outer function executes, a closure is formed, consisting of the inner function s code and references ( the upvalues ) to any variables of the outer function required by the closure.
