As a SmallTalk youngster: A few questions...

Hi All,

Learning; Please bear with me.

Scenario:

1.  Class>>User.  InstVars: #(this that other userStatus userMeta)
2.  Class>>UserManager (singleton). Instvars: users (RcIdentityBag: users)

When User is instantiated all its' instVars are populated correctly. Nested objects as well.

To insert the User into the UserManager singleton instVar I created an add: method on the instance side of UserManager to pass the User to the UserManager as per:

---
add: aUser
                 users add: aUser
---

This works and I am able to created my database of users.

The difficulty I am having is that when I want to query the UserManager db with something like:

---
RcIdentityBag(users) select: [ :each | each name := 'somename' ]
---

It seems that currently the only I know how to do this is to create a select: method in UserManager simply to pass the desired search string into the UserManager class such that I can use the Collection Classes api to do the actual work, as per:

--- Pardon the not so smalltalky code ---
UserManager>>select: aString
                | resultSet |
                resultSet := users select: [ :each | each name := aString ].
                ^resultSet
---

I believe I read somewhere that in order to avoid this clunkiness that I could refer to the users collection in UserManager via a symbol and access the api of the identitySet directly.  Something like:

---
UserManager class>>current

                                               
        UserGlobals at: #FOO put users.
        ...
---

But when I do this I am unable to do something like:

---
#FOO add: user
---

Do to doesNotUndestand exceptions.

Finally Questions:

1. Am I totally off the mark with the use of smalltalk symbols?
2. Must I create the API in the managing class to perform the specific functions I need from the collection API with respect to querying the collection?
3. Is there a smalltalk way of doing this properly that I missed (reading all the docs I can find in random order based of info I need - probably missing the finer points)?

Any nudge in the correct direction would be greatly appreciated.

Thanks!

Also if you add #FOO to UserGlobals you should be able to reference it like:
