[Oberon] IMPORT Modules: why does order matter?

Now that the main Oberon-2 features are implemented, one could (relatively)
easily create a version of the EO compiler that is *fully* backward compatible
with the “official” Oberon-2 language spec, i.e. such that any legacy Oberon-2
program can be compiled without *any* change. Such a compiler would of course
also have to add back the code that allows modules to be imported in any order.
Most of it is done, but it’s just not a high-priority item..
