[Newbies] Best way to implement two-dimensional array

[John Almberg]

Whoa... that worked, but the implications are a bit hard to digest...

So MyClass is an object in my Smalltalk image, and it can have  
variables that I can set interactively, and the values contained  
therein are now part of the class...

I keep reading that classes are objects, but this is the first time  
I've seen something that makes me realize that they are fundamentally  
different than objects in other languages. I guess because they are  
'live', in some sense, in the Smalltalk environment. That is, not  
just source code, but an instantiated object.

Talk about paradigm whiplash... I'm going to have to think about  
this, a bit :-)

Thanks!
