- // 1. We are looking in a package other than p, and p is not dot-imported.

- // We look at all imports of p to gather all names under which it is imported.
- // (In the typical case, it is imported only once, under its default name.)
- // Then we look at all selector expressions and report any matches.
- //
- // 2. We are looking in a package other than p, and p is dot-imported.
- // In this case, Q will be referred to just as Q.
- // Furthermore, go/ast's object resolution will not be able to resolve
- // Q to any other object, unlike any local (file- or function- or block-scoped) object.
- // So we look at all matching identifiers and report all unresolvable ones.
- //
- // 3. We are looking in package p.
- // (Care must be taken to separate p and p_test (an xtest package),
- // and make sure that they are treated as separate packages.)
- // In this case, we give go/ast the entire package for object resolution,
- // instead of going file by file.
- // We then iterate over all identifiers that resolve to the query object.
- // (The query object itself has already been reported, so we don't re-report it.)
- //
- // We always skip all files that don't contain the string Q, as they cannot be
- // relevant to finding references to Q.
