I posted previously on downloading the Squeak plug-in and not getting an  
image with it. The point was made that it should be all-inclusive (which I  
believe is true) but the file itself is only about 900K! I'm trying to  
figure out if the link is wrong and needs to be corrected or what.

Not a strong believer in encapsulation?<s>

Yeah, but if I want to test code that's in a method from the Workspace, I  
don't think the Inspector's going to help there.

Yeah, I know that. It just...feels wrong.<s> I guess they have no semantic  
value at all, other than what's ascribed to them. Could make for some  
REALLY obscure bugs under some unlikely situations....

It does, thanks. I welcome any other thoughts here, too.

Here's another one: Delegation. I tend to delegate like mad--years of  
Delphi programming and an aversion to the notion of identification  
("Whaddayamean an X is a Y? No it's not, it's an X!")--and I'm wondering  
if that's a bad idea for a deck of cards.

A deck of cards IS an ordered collection of cards. What I have is a deck  
of cards which HAS an ordered collection of cards, along with an ordered  
colleciton representing the as-yet undealt cards, plus an ordered  
collection of ordered collections for all the other piles (discard, hands,  
whatever is needed for the particular game). But I keep having to pass  
everything through to the master ordered collection.
