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)
