+ // another repository (i.e., a "chained" third-party repo).
+ // The question is then whether we will load such "third-
+ // party packages" (i.e., packages that are not in our
+ // repository). If the answer is yes, then we can have
+ // a pointer here. If the answer is no, then we can't.
+ // Also, if the answer is yes, we probably don't need to
+ // load as much information as for "our own" packages. We
+ // also shouldn't be showing them in search results, etc.
+ // I think all we need is to know which repository this
+ // package comes from so that we can tell the user. How are
+ // we going to capture this? Poly hierarchy of packages?
+ //
+ // 2. I believe we don't need to use a weak pointer here since
+ // there should be no package dependency cycles (and therefore
+ // ownership cycles).
+ //
+ // 3. Actually there can be dependency cycle as dependency referes not to
+ // just a package but a specific version, so for the same pair of
+ // packages dependency for different versions can have an opposite
+ // directions. The possible solution is instead of a package we point
+ // to the earliest version that satisfies the constraint. But this
+ // approach requires to ensure no cycles exist before instantiating
+ // package objects which in presense of "foreign" packages can be
+ // tricky. Can stick to just a package name until get some clarity on
+ // "foreign" package resolution.
+ //
+ // 4. As we left just the package class the dependency resolution come to
+ // finding the best version matching package object. The question is
+ // if to resolve dependencies on the loading phase or in the WEB interface
+ // when required. The arguments in favour of doing that during loading
+ // phase are:
+ //
+ // - WEB interface get offloaded from a possibly expensive queries
+ // which otherwise have to be executed multiple times for the same
+ // dependency no matter the result would be the same.
