I also think that there are situations where chaining may be very handy.
Turning back to my version of 'rectangle' class, with a function calls
chaining you may write something like

r.left( 10 ).right( 20 ).top( 5 ).bottom( 10 );
r.assign( 10, 5, 20, 10 );

I know that this looks like a Smalltalk code =), but I think it's very
convenient to write something like that - first, because you don't have to
remember the order of arguments in 'assign' method and, second, because it's
more flexible - you can assign values to any of fourth properties and these
assignments look as an atomic operation (with a semantic point of view). The
latter seems to be important quite often. Do you agree?
