+ // If the path is in src, then we may end up with multiple scopes. For
+ // example, if two configurations of the same project are being built in a
+ // single invocation. How can we pick the scope that is "ours", for some
+ // definition of "ours"?
+ //
+ // The current think is that a project can be "associated" with other
+ // projects: its sub-projects and imported projects (it doesn't feel like
+ // its super-projects should be in this set, but maybe). And "ours" could
+ // mean belonging to one of the associated projects. This feels correct
+ // since a project shouldn't really be reaching into unrelated projects.
+ // And a project can only import one instance of any given project.
+ //
+ // We could implement this by keeping track (in scope::root_extra) of all
+ // the imported projects. The potential problem is performance: we would
+ // need to traverse the imported projects set recursively (potentially
+ // re-traversing the same projects multiple times).
+ //
+ // An alternative idea is to tag associated scopes with some marker so
+ // that all the scopes that "know" about each other have the same tag,
+ // essentially partitioning the scope set into connected subsets. One
+ // issue here (other than the complexity of implementing something like
+ // this) is that there could potentially be multiple source scopes with
+ // the same tag (e.g., two projects that don't know anything about each
+ // other could each import a different configuration of some common
+ // project and in turn be both imported by yet another project thus all
+ // acquiring the same tag). BTW, this could also be related to that
+ // "island append" restriction we have on loading additional buildfile.
