The error thing.duplicate

user: the script can change it: the error says what happened in the experiment’s names, and what to write instead.

Where MIME gives it, with what its message says happened and what its action says to do ({…} is filled in from the experiment):

• in mime/build/_plan.py:

  • what happened: two things are named {…}: a {…} at {…} and a {…} at {…} (a body bound to a prim is named after the prim's last element unless it is given a name)

  • what to do: give every thing its own name: Body("<name>", prim=...)

Reading an error and reaching its full traceback: reading an error. Every code: the index.
