Care to explain for somebody dull? Cons cells don't have a header, so they need to use the mark-bit of one of their components, meaning that anything you can store into a cons-cell needs a mark-bit. I wonder how feasible it would be to use another sort of GC, like stop-and-copy, which doesn't need mark-bits... -Miles -- "1971 pickup truck; will trade for guns"
