Sorry kcott, I hope you're not offended by this, but: grandmother; eggs :)
You've 'explained' everything (that I already knew) and completely skipped over, omitted, ignored the only important part of my explanation of why state is "flawed".
It only does half the job.
I do use state for purposes other than closures: typically, once-off initialization of variables used in a single subroutine
But "once-off initialisation of variables in a ... subroutine" is a closure! Just by a slightly different syntax.
And that slightly different syntax is flawed. Which is where I started.
