hunk.code_window:         Cached objects are stored in "pickled" form, which means that the return
           value of a cached function must be pickleable. Each caller of the cached
           function gets its own copy of the cached data.
           You can clear a function's cache with `func.clear()` or clear the entire
           cache with `st.cache_data.clear()`.

hunk.after_edit:         You can clear a function's cache with ``func.clear()`` or clear the entire
           cache with ``st.cache_data.clear()``.
