Hi,

due to the absence of a namespace solution we today often prefix classes with one, two or three letters.
You all know prefixes like "Zn", "Zdc", "GLM", "Tx", "WA", ... to avoid conflicting names.

I would like to have a "::" separator within the class name to better distinguish
the class name from the prefix and increase readability at the same time. SmalltalkMT
had this solution in alignment with C++ and I really liked working with it.
So much that I would like to see it in Pharo too - maybe also as a base for future Namespace
additions.

So I modified the #isValidGlobalName in Pharo 6.0 like mentioned below to allow and support
the :: notation for classes. After that I can create classes like:

�� Seaside::Component
�� Core::Boolean
�� Model::Person
�� GLM::BrickListModel
�� Tx::FontAttribute

so far without any problem.

Do you think
��- there will be places where this conflicts or creates hazzles (tools, metacello, ...)
��- if it would be a good idea to add this to the default image?

Thanks for feedback.

Thx
T.
