Sounds nice. I especially welcome the variable mechanism for colours so that I don't have to write the hex value of today's favourite color (or its highlighted or shaded variant) everywhere I use it. I'm not sure yet if I'm happy with the lazily evaluated variables, though. In makefiles, I tend to prefer := assignment (eager evaluation) to = assignment (lazy evaluation) when possible to avoid surprises.
