On Scripting News on February 13, 2002, Dave Winer asks why avoiding tables is so important in web-design and points here. This is an attempt to answer that question. Thanks for the link and conversation, Dave! I want to make clear that I’m not saying you should never use tables. Tables are in HTML, and when you want to display tabular data, you should use them. But for layout, there are other options.

In this paper, an implementation of "Stackless Python" (a Python which does not keep state on the C stack) is presented. Surprisingly, the necessary changes affect just a small number of C modules, and a major rewrite of the C library can be avoided. The key idea in this approach is a paradigm change for the Python code interpreter that is not easy to understand in the first place. Recursive interpreter calls are turned into tail recursion, which allows deferring evaluation by pushing frames to the frame stack, without the C stack involved.
