If no coercion is currently known, then coerce_map_from() calls
_coerce_map_from_(). If _coerce_map_from_() returns a map, then that map
becomes the coercion map. If it simply returns True, then the coercion map
is constructed by using _element_constructor_() as the definition of the
map. In ei

An empty line is inserted before the multi-line output in the method
write_format_data of IPython.core.displayhook.Displayhook. I guess
self.prompt_end_newline should be True for the Sage CLI.
But the method write_output_prompt of
IPython.terminal.RichPromptDisplayHook sets this to False. I gue

IMHO there ought to be possible to return "Unknown" as the result.
Indeed, in many cases such an exact computation is not feasible.

I put the following comment to the IPython issue:
The method write_output_prompt in the class RichPromptDisplayHook sets the
attribute prompt_end_newline to true when the output prompt ends explicitly
with \n. In Sage, the output prompt is just empty string. I think that in
this case too,
