A simple solution (sligthly inefficient). Rewrite

	with a.b.c begin
		d = 10 ;
		e.f = 3.4
	end

as
	{
	 struct <whatever> *s = &a.b.c ;
	 s->d = 10 ;
	 s->e.f = 3.4 ;
	}

where <whatever> is the type of a.b.c. If you like, I guess to can define a WITH macro 
which will do that automatically (modulo the name of the local structure pointer).
