Not for the last 12 years or so. It's expanded to
while (defined ($_ = <SOME_FILE_HANDLE>)) { ... }

    Technically, you're both right, because

    while ($_ = <SOME_FILE_HANDLE>){ ... }
    is expanded to
    while (defined ($_ = <SOME_FILE_HANDLE>)) { ... }

    But all this is irrelevant. It's not the magical expansion of <> that causes the scalar context.
