Why doesn't this work? :)

[Chris Lambacher]

I think what you really want is:

try:
	# this will fail and be caught
	# below, weeee
	import foobar

except ImportError, error:
	class foobarclass:
		def __getattr__(*args, **kargs):
			return None
    foobar = foobarclass()

print foobar.bg


foobar in your version is a class.  By making it an instance, the __getattr__ method is properly called.
