PyObjC

I worked around the missing selector by passing "missingSelector:" as the 
argument.
Since it shouldn't get called without a modalDelegate, that should be ok as 
a workaround.
Next question: why is the selector for the contextInfo: argument 'i'?  The 
objc spec is for this to be a (void *), but I am prevented from passing 
None here (workaround: pass 0 instead).

Summary: beginSheet fifth arg type shouldn't be int

Initial Comment:
In
NSApplication.beginSheet_modalForWindow_modalDelegate_didEndSelector_contextInfo_,
the type for the final argument is specified as 'i'
(integer) even though the Cocoa docs list it as (void
*).  This setting prevents None being passed in this
position.  Easily worked around by passing 0 instead of
None, but could be a problem in case someone wants to
pass something nontrivial instead.

Summary: Unable to send nil in selector argument

Initial Comment:
If an objc function has a ':' (selector) as the type of
one of its arguments, it should be possible to pass
None as that argument to produce a null selector, but
this is currently disallowed.  The empty string doesn't
work (pyobjc tries and fails to interpret it as a real
selector).  An example of a method for which this is
useful is
NSApplication.beginSheet_modalForWindow_modalDelegate_didEndSelector_contextInfo_
(fourth arg is selector).

How do I set a selector argument to be empty?  E.g. the Cocoa docs for 
running custom sheets (Cocoa Developer Documentation >  User Interface 
Elements >  Windows and Panels > Sheets, listing 3) show the following code:

    [NSApp beginSheet: moreInfoSheet
            modalForWindow: window
            modalDelegate: nil
            didEndSelector: nil
            contextInfo: nil];

here the fourth argument didEndSelector: is a selector.
When I attempt to translate this code into pyobjc, I get

NSApplication.sharedApplication().beginSheet_modalForWindow_modalDelegate_d
idEndSelector_contextInfo_(self.sheet,self.window,None,None,None)
TypeError: expected a ObjC method or a string for argument 4: its typespec 
is ':'
