Pliant is a language that is expected to be usable as a scripting language (let's say Python), as a system language (let's say C) and as a logical programming language (I mean rewriting capabilities of let's say Lisp).
With a single language that can be resonably used in all areas, one can build a set of applications with unprecedented consitency and customizability (because the macro language is the core language itself), and it's now what's happening. As an example, the full featured dynamic HTTP server is roughly 1000 lines of code.
About status: the language is now fully usable provided you have a i386 based computer. The set of standard applications that turn it to a full system is still under construction (already available for testing, and usable around 2001). See Pliant web site for extra details.

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.
