It was part of a fairly long progression in changes to the
command line execution support :)<br>
<br>
Top level package execution with -m came first in 2.4,
arbitrary package execution for -m arrived in 2.5 (along with
the runpy module), directory and zipfile execution (by
supplying a valid sys.path entry as the "script" command line
argument) was added in 2.6/3.0, and finally officially
supported package execution via -m only arrived in 2.7 and 3.1
(a broken version of the last accidentally existed in 2.5, but
that was just a mistake that arose when merging the import
emulations in runpy and pkgutil, and had a side effect that
violated at least one of the import system invariants).<br>
<br>
In the specific case of directory and zipfile execution,
discussion happened on the tracker: <a moz-do-not-send="true"
href="http://bugs.python.org/issue1739468">http://bugs.python.org/issue1739468</a><br>
<br>
It was never brought up on python-dev because Guido was
participating directly in the tracker discussion.
Unfortunately, we then also forgot to mention it in the
original version of the 2.6 What's New doc, so the vast
majority of people missed the addition :(<br>

Hi Nick,<br>
<br>
thank you very much for this story and the link to the issue
tracker!<br>
A very good move for Python which is really not mentioned enough<br>
to make people more aware of a great feature.<br>
<br>
I think part of this discussion should get a more prominent place<br>
for gems that can be found without knowing what to search. ;-)<br>
<br>
Is the issue tracker permanent enough to reference it?<br>
Maybe there could be some auxiliary info page with proper keywords<br>
that collects links to relevant discussions like this.<br>
Do we have such a thing already?<br>
<br>
ciao - chris<br>
