Answer 1

If you're nesting a function, say function2 inside function1, it doesn't become available until function1 is called. Some people might consider this a feature, as you can do something like "unset function2" at the end of function1 and its scope is completely local to that function (can't be called from elsewhere). If you want to call the function elsewhere, there's probably no need to nest it anyway.
