Alexander Belopolsky <belopolsky [at] users> added the comment:

Apparently this was introduced with r51625 :

r51625 | guido.van.rossum | 2006-08-26 16:37:44 -0400 (Sat, 26 Aug 2006)
| 4 lines

Inspired by SF patch #860326, make the exception formatting by
traceback.py be closer to the built-in formatting.
A few unittests had to be fixed, too.

------------------------------------------------------------------------

When doctest is imported as __main__, traceback does not prepend
UnexpectedException with doctest. prefix. Attached patch fixes the
issue by explicitly reimporting doctest in the 'if __name__ ==
"__main__":' clause.

This is rather inelegant and a better solution would probably be to use
python -m doctest for something other than self test. For example,
running doctest.testfile on command line arguments would be a reasonable
use, but python -m doctest Lib/doctest.py may still have a problem.

R. David Murray <rdmurray [at] bitdance> added the comment:

python -m doctest does accept file arguments. Running the self-test is
the default if no arguments are supplied.

python -m doctest Lib/doctest.py passes.

So perhaps we should just remove the default and instead issue an error
message about missing arguments.
