Hi Francois,

Yes, the dictionary is the mechanism for reusing objects (including
theorems) in an article file.

To address your question about naming theorems, the article format is
intended to be written and read by tools, not humans, so there is no
need for a human-readable name. To bridge the gap an article compiler
must create a mapping from human-readable names to integers
(dictionary keys).
