  1. Make a file code.sage with code in it.
  2. Type attach('code.sage'). There is a weird warning that has nothing to do with code.sage, but attach pretends to work.
  3. Try to use something from code.sage -- it does not work.

Note that attach works fine in Sage worksheets and sage on the command line.

Attach fails in the same way using upstream plain jupyter, so this is a Sage bug or a problem with our kernel:

Still broken, exactly in the same way, with SageMath version 8.8, Release Date: 2019-06-26.

NOTE: the load function works; it's just attach that doesn't... which is pretty serious, since that's an amazing command.
