[PEAK] What do you use 'offerAs' for?

[Erik Rose]

I can't think of any uses that wouldn't be served just as well by  
dynamic variables. There are presently 5 uses of offerAs in my  
project: they offer connections to SQL DB's, the logged-in user, the  
HTTP request, and one other thing I'm too ashamed to mention. ;-)

So, just to make sure I'm getting this straight...

To replace the use of `offerAs=[ISQLConnection]`, you'd do something  
like this...
     with storage.iSqlConnection.push(someSqlConnectionIveGotAholdOf):
         callStuffWhichUsesTheConnectionFromStorageDotISqlConnection()
...where in the storage module it would say...
     iSqlConnection = context.Variable()
...?

Do you propose to basically keep a global around for each interface,  
like I posit above, or do you have something whizzier in mind?
