Right, in that case, it would work, but in my experience, it is important to be able to apply conditionals to more than just requirements (packages definition and so on). I am not suggesting something very complicated (we don't want to re-create a language), but more something like cabal (see conditionals in http://www.haskell.org/cabal/users-guide/developing-packages.html#package-descriptions), or even RPM (http://www.rpm.org/max-rpm/s1-rpm-inside-conditionals.html). This has the advantage of using something that has already been battle-tested for several years. But again, syntax is a really minor point, and what matters the most are the features. I was not able to express what I wanted with yaml for bento, but would be more than happy to scrap the custom format if someone manages to.
