New Paradigm for Comparing the Expressive Power of Languages
The community folklore abounds with informal claims concerning the expressive power of certain programming languages. Given that just about all languages under discussion are Turing Complete, Felleisen introduce the concept of »macro expressiveness« to provide a framework for more principled comparisons between languages .
While Felleisen's work was groundbreaking, we have built upon Diggin's recent work on the Cat language  to develop a comparative framework that not only correctly captures many informal notions of expressiveness, but is durned cute at the same time. Language features that can be encoded using our methodology are said to be »cat macro expressible« . We illustrate the technique by showing that most features of C language  are cat macro expressible as »im in ur stackz overflowing ur bufferz« . Finally, we provide evidence that the massive parallelism inherent in the Internet can be harnessed for the generation of programming idioms that are cat macro expressible .
