I should have checked this in a 0.9 tree, 0.9 doesn't even include a 
definition
of this protocol. That leaves us one alternative: even more explicit 
markup.

Add 'windowShouldClose_ = objc.selector(windowShouldClose_, 
signature="c@:@")'
just below the definition of the method. This will tell the bridge that 
this
method returns a boolean instead of an object.

	class MyDelegate (AutoBaseClass):
		# ....
		def windowShouldClose_(self, sender):
			return 0

		windowShouldClose = objc.selector(windowShouldClose, signature="c@:@")

Another thing that will probably work: return None if the window 
shouldn't close
and any other value if it should.
