Now imagine that instead of burying the search state in invisible globals you
would like to expose it as an IN OUT parameter ...

I agree that in a carefully designed program procedures with return values
would be rare. As well as gotos which are allowed.

I agree that they are clumsy (in most cases), but the alternative is pointers,
which are much more worse.
