In previous versions, extension modules with the file 
extension '.dll' could be imported using a 
single 'import' statement.

In 2.5a1 this seems to have changed - here's an 
example:

>>> import minx     # Implemented in a .dll - fails 

Traceback (most recent call last): 
  File "<stdin>", line 1, in <module> 
ImportError: No module named minx 

>>> import imp    # Workaround 
>>> import os 
>>> minx = imp.load_dynamic('minx', os.getcwd() 
+ '\\minx.dll') 


I would really like this to remain the same; if that's 
not possible, it would be helpful if the change itself 
and a suggested approach were to be included in the 
documentation.

I believe this was an intentional change in rev 43622.  I
don't see any doc associated with the change however.  I
also thought it was mentioned on python-dev.  Martin,
shouldn't this be documented at least in Misc/NEWS?  I
couldn't find anything.

Note that rev 43622 added a comment to dynload_win.c
explaining why it was done:

"""
/* Temporarily disable .dll, to avoid conflicts between
   sqlite3.dll and the sqlite3 package. If this needs to
   be reverted for 2.5, some other solution for the
   naming conflict must be found.
"""

Tim mentions the rationale for the change; the Misc/NEWS
entry is now in r45574.

svenn, why do you need it to work that way? Could you change
your code/application/whatever so that it works with .pyd
files instead?

Hi loewis,

I', sure the .pyd extension will work fine - my original 
comment was due to the fact I didn't realise it would work 
as today if the file extension was changed; I was (wrongly) 
assuming I would have to use the approach indicated in my 
example, which seemed a little less intuitive than the 
simple "import".

Closing as "Won't fix", then.
