I consider this change to be a bug fix (but feel free to remonstrate if you disagree). > > The main problem here in 5.12 and earlier is that tied $scalar cannot reliably be used to see whether a scalar is tied, because a typeglob might have been assigned to or returned from it. The same happens with untie $scalar, which may or may not work, depending on what was last assigned. I fixed those and also made tie() match. This means that tie $scalar will always tie a scalar, and, if the scalar has been used before, you don’t have to check its value to see whether you need to undefine it to be able to tie it. >
