Sorry if this is a stupid question, but what is up with this:

calendar.py defines __all__ this way:
__all__ = ["IllegalMonthError", "IllegalWeekdayError", "setfirstweekday",
"firstweekday", "isleap", "leapdays", "weekday", "monthrange",
"monthcalendar", "prmonth", "month", "prcal", "calendar",
"timegm", "month_name", "month_abbr", "day_name", "day_abbr"]
Only those names are imported with '*'.

Oh, I didn't realise modules could do that. Thanks.
Do you know what the rationale behind not including 'Calendar' is?
Let's see... at line 561 of calendar.py there's something suspicious:
--->
# Support for old module level interface
c = TextCalendar()
firstweekday = c.getfirstweekday
def setfirstweekday(firstweekday):
try:
firstweekday.__index__
except AttributeError:
raise IllegalWeekdayError(firstweekday)
if not MONDAY <= firstweekday <= SUNDAY:
raise IllegalWeekdayError(firstweekday)
c.firstweekday = firstweekday
monthcalendar = c.monthdayscalendar
prweek = c.prweek
week = c.formatweek
weekheader = c.formatweekheader
prmonth = c.prmonth
month = c.formatmonth
calendar = c.formatyear
prcal = c.pryear
<---
So, it seems that "from calendar import *" is reserved for the "old
interface" (i.e. non-OO).
