And I believe this is also true for some other plugins. The question becoms where and how should the debug printing happens in that case. I'm sure the question is not MELT specific. Imagine a plugin (coded in C) which uses some database, or some web services, or provide a web or a graphical interface. Then its initialization code also need debug printing.
