I plead guilty to having tried them out without giving feedback! So,
here it is:
They worked, as far as I could tell. I found them quite intuitively
designed (I have used C++ namespaces and Java packages before).
There is just one problem, from my point of view: they force one to
import everything global (lists, io, etc.), or add a . in front of
these modules (I couldn't get import_all to work for the global
package). As I am sick of keeping track of #includes and imports, I
enjoyed this not being necessary in Erlang. And I did not much like
the look of code peppered with the . prefix (just a matter of taste).
So, I am not using them for the moment.
However, I have not written large volumes of Erlang code. Do
those people who have feel a need to have packages? You seem to have
survived without them so far!
