Oh, that’s an interesting take. I’ve long been looking for newer developments on Awk’s clause structure, and this seems like an interesting take (though I’m unclear on whether I can have multiple begin/end clauses, which are the best thing about Awk’s version). It also finally connects this idea to something else in my mind—specifically advice[1] and CLOS’s :before/:after/:around methods[2]. (I guess Go’s defer also counts?)

It seems not:

Given:

    function Fred {
        begin {
            echo "hello from begin1"
        }
        begin {
            echo "hello from begin2"
        }
        process {
            echo "does the magic"
        }
    }
    $bob = @("alpha" "beta")
    $bob | Fred

    $ pwsh fred.ps1
