Thank you for response.

As I understand in the first line ("a=1") a temporary object has been 
created and then disposed. As a result we get "a" global variable of 
Number type. It is an object - so we can do "a.a=1". But "a.a" - is not 
an object. The same situation - but different result, from my point of 
view.

Are all global variables - objects?
