    No. It is a fundamental computer operation.

    Anyone who finds it difficult to understand should not be a programmer.

    Would you use a lawyer who didn't understand tort or habeas corpus?

    Or an accountant who didn't understand double entry?

    Or a doctor who didn't know about the lymphatic system?

      You're content with  $? >> 8 , well bully for you, System::Command uses it also, because I don't want to, I'm not a bash programmer, I don't want to do things the bash way, anymore than I want to sharpen my own knives

        You equate deploying an entire module in order to avoid using a shift operation, with "sharpening your own knives".

        More like you want to use disposable plastic spoons.
