As far as I understand there is s.th. called separate 
compilations. Your program may is compiled in parts. Your logic 
which loops over the modules only knows which modules are 
available at the specific point in time.
I do not know whether there is some functionality which tells you 
all modules available at compile time. But if this functionality 
exists, you (the developer) has to be aware of separate 
compilation and should have a plan how to mitigate. Either do not 
use separate compilation or always force recompilation of all 
source code files...

In would really like to have such functionality and also the 
possibility to express in code: always recompile this part of 
code (the loop over the modules) even in separate compilation. I 
do not know whether that is technically possible...

Kind regards
Andre
