Assignment 4: Improve code for HigherOrderLists

Assigned: Tuesday 27th January; due Tuesday 3rd February

You are required to work with a partner on this assignment.

Make two improvements to the higher-order lists implementation that you can get from SqueakSource and which is also attached to this assignment.

An "improvement" is defined as

a bug report (which means some text and a test that ought "obviously" to pass but which currently fails), or
a bug fix (which makes the failing test pass), or
a place in the code where the current implementation does not meet the high standards that we have set in this class, and a refactoring that improves the code while still allowing all of the tests to pass.

Turn in a Monticello package and some text describing what you have done. Don't forget to name all of the students who worked on this assignment. The reason for working with a partner is to give you the courage to tell your professor that his code is buggy or that it "needs improvement".

To get the code from Squeaksource, tell Monticello to "+Repository", choose an HTTP repository, and enter the following details:

MCHttpRepository location: 'http://www.squeaksource.com/AdvProg2009' user: '' password: ''

Then you should be able to open a repository browser and load the package.

If you prefer to use the attachment, the simplest way to extract the code from it is to drop the .mcz file into your package-cache, select the package-cache in Monticello, and load the package just as you would from a real repository.

Turn in your package by email to cs410aph @ cs and use the commit comment to give the names of BOTH STUDENTS and a descritpion of what you have done.
