You believed right - I do indeed lack the vision of others to foresee any practical need to attach and detach within a recursive function, except perhaps for my own amusement. Should I do the recursive call in between the attach and detach, I wonder? Wouldn't it all be fun, watching that search path grow and grow, before the function eventually hit the first detach! And just imagine the hilarity you could have, attaching and detaching at different positions! I could have a thousand identical data sets, all called Eric!!!
It's one of the many situations in which I would very much like to get a warning or error message, pointing out to me that I had absolutely no idea what I was doing. Surely that's what warnings are for? For those of us who wonder why our code doesn't do what we think it should, until a long time after the deadline?
