Qualification rewrites a package's own names wherever they are used and has to stop at a binding. Nothing refuses a renamer that does not: the program builds, runs, and reads the top-level name instead. The package in shadow-pkg.flan binds locals called limit and sink over its own constant and var, and the four numbers separate the two halves — dropping the shadowing check in the expression renamer gives 5, dropping it in the place renamer moves the 20 onto the package's sink.
