Thanks for the hint, but I'd like to refrain from external
libraries as much as I can, especially for something simple as
a simple number inside a data structure.

I might also achieve something like this by eio from pecl, through
e.g. eio_dup2, but it's just unrealistic overkill to ask for a full
extension installation for just 1 one trivial piece of functionality.
