Can everyone please stop shoehorning in random xkcd comics where they don't belong?

At the risk of introducing another level, I will mention that these comments are very Meta :)

>>> Foo = type("Foo", (FooBase,), {'bar' : 42})

is not equivalent to what the blog post says it is to. FooBase should be defined before running this, and the blog post's equivalent make it look like this statement defines FooBase as well.

I think you neglected the line in front of it, which does define FooBase.

   1. >>> FooBase = type("FooBase", (object,), {})  
   2. >>> Foo = type("Foo", (FooBase,), {'bar' : 42})

Although I am not a python expert, so you may be right... in which case, how does line one not work?

I stand corrected - I was skimming and didn't notice. The example is correct - I was wrong.

For me this article was written in reverse. For an intro I'd love to have had the 'code smell' example first to establish why I might care and when I might need this, and then dive into an example.
