4e49ec135dda93676ceb95f4ade7496139c2bef7 is the first new commit
commit 4e49ec135dda93676ceb95f4ade7496139c2bef7

    Fix infix:<xx>(..., *) for empty Slips
    
    The current code makes the assumption that when a Slip is encountered,
    it is non-empty, and it saves it in an Array and shifts from that array,
    to obtain next value. This causes a Failure when the Slip is empty and
    there is nothing to shift.
    
    Fix by checking whether we can shift and returning IterationEnd if can't.
    
    Fixes RT#130619: https://rt.perl.org/Ticket/Display.html?id=130619
