No, no, no. This happens only *without namespaces*. What you describe is
the standard behaviour of Gambas:

The first class 'Mail' is loaded. The second class 'Mail' which is
loaded afterwards overwrites/inherits the first one.

Sometimes this is a very nice feature. But it is deadly if you want to
use a library with code which was written by someone else which you can
download from Gitlab and integrate in your program.

Because if you load such a library classes with the same names ('Mail'
in the library and 'Mail in your program') will inherit/overwrite each
other and this will crash your program with high probability!

This happens with the current Gambas we all work with.

You can use them independently of each other. There is *no inheritance*.
It is the great advantage of namespaces, again:

*No inheritance*

(To be precise: No automatic inheritance.)

If it helps you then you can see it as if you would call the classes:


Alles Gute
