Hi,
I'm an experienced Java developer and I code in Smalltalk in my spare
time. I'm used to using
namespaces to structure my code with Java and the lacking of it in
Smalltalk was never a problem for
me.
By my exprience, I don't think namespace support is necessary or a good
think.
The lacking of namespace support forces developers to think (and thus to
name) their class in a more
strongly way: a class name should vehicle the concrete (technical or
business) concept it represents
and simple name should be avoided. Event the most general concepts
depend upon the context in
which they are used, so their name should be prefixed by a name or
keyword that identifies this
context. This is just my humble opinion.

Sorry for the noob questions...
What do you do if you want to import 2 discreet packages into your image and
each contains a class of the same name?
As Squeak/Pharo haven't namespaces, you should modify some of them to
other name so that they don't clash. Either rename the class to
something different of add a prefix to one of them. This is the reason
why many packages start by choosing a prefix (2 or 3 chars) that are
used in all the classes of the packages:
W* for Seaside
Ma* for Magma classes
etc.
If you have a .st file with the source code of one of them then open it
in a good text editor and add a prefix to all the classes.
Or load one package in an image, refactor the classes to a new prefix
and then load the second package.
You can also explore the namespaces implementation that was developed in
the last google summer of code. A presentations and a screencast was
available. Search the archives for them.
Cheers
