Hello, I think that the article entitled "Data Memory Paging Management" at http://www.embedded.com/2000/0001/0001feat2.htm may be related to this thread. Also, I think that using indentation for scoping is a nice idea,as it is done in Python scripting language. "Life is better without braces" they say.
