The main goal is to push the package variant logic from internal/lsp into internal/lsp/source so all users of internal/lsp/source benefit. "references" and "rename" now have top-level source.References() and source.Rename() entry points (as opposed to hanging off source.Identifier()). I expanded objectsAtProtocolPos() to know about implicit objects (type switch and import spec), and to handle *ast.ImportSpec generically. This gets rid of special case handling of *types.PkgName in various places. The biggest practical benefit, though, is that "references" no longer needs to compute the objectpath for every types.Object comparison it does, instead using direct types.Object equality. This speeds up "references" and "rename" a lot. Two other notable improvements that fell out of not using source.Identifier()'s logic: - Finding references on an embedded field now shows references to the field, not the type being embedded. - Finding references on an imported object now works correctly (previously it searched the importing package's dependents rather than the imported package's dependents). Finally, I refactored findIdentifier() to use pathEnclosingObjNode() instead of astutil.PathEnclosingInterval. Now we only need a single call to get the path because pathEnclosingObjNode() has the "try pos || try pos-1" logic built in.
