* Since function definitions can be nested we use a stack storing if "this" is valid in the current context.

*
|
|
* Example:
|
|
*
|
|
* function a(this: number) { // valid "this"
|
|
* function b() {
|
|
* console.log(this); // invalid "this"
|

* }

* }

*
|
|
* When parsing the function declaration of "a" the stack will be: [true]
|
|
* When parsing the function declaration of "b" the stack will be: [true, false]
