I would guess that something like the asked-for counter could be useful if one is allocating ranges of addresses to things, for example heap nodes when compiling a function body to instructions to build a graph. Why not have a monad m a = Int -> (a,Int) which is a state monad plus the operation bump : Int -> m Int bump k n = (n,n+k) Rgds, Peter Hancock
