I haven't really read the parser yet, but I imagine that after the
detection of keyword "private", the parser/interpreter will call
"rb_define_private_method()" instead of "rb_define_method()".  Therefore,
in a similar way, after the detection of the keyword "private", any newly
detected "@var = ..." will not call "rb_iv_set()", but something like
"rb_private_iv_set()" which just simply writes the data in a separate
hash.  Now, the "... = @var" case is a little bit more tricky, but I think
it should invoke "rb_private_iv_get()" before searching using
"rb_iv_get()".

I must be missing something.  Why can "x = 1" imply "self.x = 1"?
