- Because `KtModule`s and thereby sessions may depend on each other
cyclically, we must not create a session during the creation of
another session. Otherwise, let's say session A and B depend on each
other. Then we get the following nested creation: session A -> session
B -> session A -> session B, and so on.
- Dependency symbol providers are in part taken from dependency
sessions. Hence, we have to create dependency symbol providers lazily.
- For the creation of dependency symbol providers we only need to access
the non-dependency symbol providers of a session dependency, so we
don't need to access the dependency's dependency symbol providers.
Hence, the lazy construction won't run into issues with cycles later
on.
