What jumps into the eye is that in the testscript t/sysinfo_proc.t the
use of tie() happens before the package is parsed.

What jumps into *my* eye is that it says tie $handle and $handle is a scalar. It should be tie *$handle.

tie $handle used to tie a handle if a typeglob had been assigned to $handle. 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.

This should have been ‘fixed’ by 7850f4d, which simply reverted a bug fix.
