The child cannot possibly write to the variable in the parent process. This child has no access to the parent's memory space even if it had any understanding of Perl variables. That's what open3 normally creates pipes for you.

    [marto]: exactly
    [Veltro]: marto Well, what I mean is that I can remember reading about it somewhere and everyone responding that this could not be done. A while later everyone was proudly showing their app. Look what I can do!
    [marto]: some statements are true at the time of writing. Some of these apps that 'determine' what you're playing just sample audio input and pass it to a cloud service for processing, so technically that 'app' isn't doing it.
    [Veltro]: marto depends on how you define app. Doing the processing somewhere else, so it is not the same app? I don't think like that anymore.
