=======

Smart modes:

- strict: don't allow to introduce more build-time broken things (imports of non-existent
  entries, entries that throw at evaluation). It's allowed though to create functions
  that refer to non-existent entries. Rename of entry or import entails changes of all
  usages of this name (smart rename). If smart rename is impossible (e.g. name
  collision), we abort the whole operation.

- tolerant: allow to introduce more broken things but also try to smart rename. If smart
  rename is impossible, then do it partially (wherever possible).

- off: allow to introduce more broken things and don't smart rename. This is almost
  equivalent of plain text editing.


"Smart rename" implies:

  - on entry rename, fix all its usages within the same module, all its imports and all
    the usages of the imports in other modules;

  - on import rename (or alias rename), fix all the usages of the imported name;

  - cannot delete an entry if something depends on it at build time;

  - cannot add an entry with non-existent build-time dependencies.
