    With the advent of nested_scopes, I believe you can accomplish this by
just embedding a 'def' in either the __init__ or the collection.do function,
making your code as readable as that smalltalk code was. :)

For instance:

class Dummy:
    def __init__(self, collection):
        def DoThisAndDoThatToItem(item):
            item.DoThis()
            item.DoThat()

        collection.do(DoThisAndDoThatToItem)

Now. Is that readable? Its 'eh', but its far more readable then the
Smalltalkism of 'named code blocks', and it doesn't seperate that function
def from its one and only use, which is your other problem.
