For OOP features it might be nice if we can iterate all classes that

Although the question then is how to construct instances of these
classes. Maybe the factory pattern is better for this.
Just iterate all classes, like ClassInfo.find does. Add a condition to
check if a given class implements a given interface. If the correct
class if found create it with Object.factory. Tango contains a module,
tango.core.RuntimeTraits, with a function that checks if a class
implements an interface. I'm pretty sure that Phobos has something similar.
We could create a standard plugin interface in Phobos or druntime,
something like:
interface Plugin
{
void initialize ();
void terminate ();
}
Every plugin should implement this directly or indirectly. "initialize"
would be called just after the plugin is loaded and "terminate" would be
called just before unloading.
