I know more or less what you mean. And probably the
pattern also allows returning an object that is different
from "this", to model statechanges etc..

But I guess the "this" variant of the pattern only
solves a problem when the target expression is complex.
So in case I do:

	a[x].append(b);
	a[x].append(c);

I can replace this by the following, provided a and
x are not volatile:

	a[x].append(b)
	    .append(c);

And I get a little performance improvement, since
a[x] is only fetched once. But again, I could do this
by hand, if the "this" pattern were not implemented:

	h = a[x];
	h.append(b);
	h.append(c);

Bye
