I see no downside to having prereqs specified as an array rather than hash, but I'm not sure if I want want to say that clients *must* install in that order or *may* use that order to guide dependency resolution. One issue may be that it won't be clear where in the array to put dynamic (OS-specific) dependencies. I'd say maybe for 2.0 we change to an array, and then we take a bit longer to figure out how to use the sequence in practice. So, I'm narrowly supportive, but see a lot of thorny issues to figure out. David
