Re: [perl #22290] scalar untie doesn't always work

* There is nothing in the documentation to say that it should

* Thats because when FETCH is called perl needs somewhere to place the
* result before actually using it. In the case of a tied SCALAR it uses the
* scalar that is tied. So there is now way that the old value can be
* reverted to. After untie, a scalar will always hold the last value

Okay, I can live with that.  Please close this bug out.  

I think I've got a couple more related to TIESCALAR, but I'll
submit 'em separately when I've got good test cases.

Thank you for the prompt response!
