You can't do any *dynamic* initialization.
You can do static initialization. As a rough equivalent, you
can do the kind of static initialization legal in "C" code, where
there is no run-time elaboration, though there is link-time
initialization of constants and variables.
The goal of "preelaboration" is to eliminate the need to execute
a run-time elaboration routine for the specified package, and rely
strictly on the kind of initialization that most linkers/loaders can
perform.
