Are you referring to Chaos/Order [1]?

I think macro composition and argument binding like that supported in 
Chaos/Order (forgive me, I'm not really sure what the difference is) 
would be great.  I remember another individual posting a link to a 
preprocessor library in the past on the developer's mailing list that 
did something similar [2].
