To summarize, here are the keypoints we have discussed:
1. The scope chain is a sequence of objects that Flash will inspect when it
looks for a variable.
2. When a function is created, the current scope chain is attached to it.
3. Each time a function is executed, a new object, called the activation
object, is created to hold all the local variables and this
object is placed on top of the function's attached scope chain.
4. When nesting functions, the activation object of the outer function is
placed in the scope chain of the inner function.
5. If the inner function gets attached to a persistent object as a method, or
is returned from the outer function, then the inner
function becomes persistent and with it the activation object of the outer
function. This leads to memory waste.
6. To avoid memory waste, a simple solution is to not use nested function but
create function externaly instead and attach
references only.
