Well, brdfs can just take the form of functions that can appear
*within* a shading language. For example, taking an input direction
vector and a normal, and giving you an output reflected vector +
probability. It's up to the shader writer to use them in a sensible
way.

Check out this video on houdini's new physically based rendering
feature in Mantra, you can sample bsdfs in their shading language:
