Phil Frickey has written “Structuring purposive statutory interpretation: An American perspective,” 80 Australian L.J. 849 (2006). Here is the abstract:

Sections 15AA and 15AB of the Acts Interpretation Act 1901 (Cth), and State analogues, provide that statutory interpretation in Australia is guided by considering statutory purpose. Professors Hart and Sacks developed the most thoughtful approach to purposive statutory interpretation in the United States. Their model sheds light on a number of important questions concerning how the Australian purposive approach might best be implemented.

This article looks like it would be a nice introduction to U.S. statutory interpretation issues in comparative perspective.
