New submission from Keith Prussing:
When a module is run under pdb in Python 3, __package__ is set to the empty
string instead of None. The attached minimum working example depicts this
behavior. The results are summarized in the following table.
=============== ====== ======
Command Py 2 Py 3
=============== ====== ======
python None None
python -m '' ''
python -m pdb None ''
pdb None ''
=============== ====== ======
The behavior I expected was for the Python executable to treat the input file
as a script and not a module. My rationale is that pdb is loaded as the
executing module that accepts a script as its argument. Per the help, only one
-m option is allowed when launching python.
