this doesn't really save typing - instead of typing self you have to
type the local declaration.  worse, this introduces extra syntax (after
all, you still need ".").

but more importantly, having "self" is good for the soul.  in most other
languages objects function in some "magical" manner.  having self makes
the mechanism clear - which is helpful both to newbies understanding OOP
for the first time, and to fools like me that get easily confused when
things happen behind their back...

ps it doesn't have to be "self", afaik - you could use just "s" to save
key presses.... :-)
