That we cannot share code which contains classes with the same name. If
I share a library with a class 'Mail' and you want to use it (because it
solves a special problem you have) and at the same time your project
also contains a class 'Mail' your code will break with high probability
if you load my lib.

> Are namespaces the only tool we can use to solve said problem?

No. We can name our classes in an very individual way:

Class DimitrisAnogiatisMail
Class ChristofAtDeganiusMail

(this is poor man's namespacing – nobody does that ... wait ... except
Microsoft in the Windows Registry, am I right?)

Alternatively you can rename the classes in your project so that their
names do not collide with names of classes of foreign libraries you load
into your project.

Alternatively you do without loading foreign libraries. This is what
currently is done in the Gambas world.

None. Existing code will* behave as always. There will be* a few new
commands and a new operator.

No.

Alles Gute
