Now, depends on whether you want custom BRDF in deferred on 1) all your objects (easy) or 2) only some of your objects (harder).

1. change BRDF for everything

That's fairly easy. The actual object shaders more or less just fill the g-buffer (and in Unity 4.x deferred lighting, combine textures with the lighting buffer in the final pass). The actual BRDF is in the "light shader". Start by copying the built-in light shader (4.x deferred lighting: Internal-PrePassLighting.shader; 5.0 deferred shading: Internal-DeferredShading.shader) into your project. In 4.x, put it into Resources folder so it's included into the build; in 5.0 point Unity to use that shader under Project Settings -> Graphics.

Change the shader to do different BRDF.

Reader Macros in Common Lisp

This post also appears on lisper.in.

Reader macros are perhaps not as famous as ordinary macros. While macros are a great way to create your own DSL, reader macros provide even greater flexibility by allowing you to create entirely new syntax on top of Lisp.

Paul Graham explains them very well in [On Lisp][] (Chapter 17, Read-Macros):

The three big moments in a Lisp expression's life are read-time, compile-time, and runtime. Functions are in control at runtime. Macros give us a chance to perform transformations on programs at compile-time. ...read-macros... do their work at read-time.
