The Pliant programming language, created by Hubert Tonneau, is based on a dynamic compiler, which makes it act like it is interpreted. The default syntax is almost trivial, and based on indentation, so it is an off-side rule language. It is reflective: Pliant programs can modify the parser, compiler, code generator, and the code optimizer.
Pliant's core advantage is its ability to allow several levels of programming, from low-level instruction lists, to high-level expression manipulation. Thus, it stresses the "compiling rules" definitions using "meta" functions (functions run at compile time to compile an expression) and "active types" (types having their own compiling scheme).

Pliant - Goal: new generation programming language. Main idea: instead of making a new language with a few new interesting features, make a very tiny, highly modular language with a trivial syntax, where most advanced features can be written in the language, as modules.
