Hi Adam,

I'm sure a lot of this is because EMarket was a 1.x product that has
seen relatively little change, in basic structure, since. I'm working
on some patched to allow (1) ZClasses to act as MarketItems and
Shoppers and (2) ZPatterns integration so that most objects can
be optionally stored in RDBM
Steve,
If the attribute is immutable, just define it as
a 'class' variable, rather than in the constructor.
e.g.,
class Foo(.. ):
newAttribute = 'hello?'
You can of course *change* it in the constructor for new
object, but all your old objects will just use the class
variable.
Hi Shane,
This is great.. it does what I wanted to do, but by making a
'fixed name' folder, (a la, 'acl_users'), to do the trick. It also
works a lot more like a 'real' CVS folder. Cool. And.. icing on the
cake... you can put it in any kinda container! Double Cool!

Hi David,
I think the design is flawed from the outset and should be
