It's not that hard to figure out an order to permute the arguments on the stack before a tail call that minimizes that number of moves and temporary locations. Lmlc did this 20 years ago. :)

Right, and that's what GHC does too, with a strongly-connected-component analysis of the dependencies between assignments of the args for the tail call. Cheers, Simon
