Hi,

    my $arrayref = <a b c>;

    for @$arrayref {...};    # loop body executed three times, of course
    for ($arrayref,) {...};  # loop body executed only one time

    for ($arrayref)  {...};  # loop body executed one or three times?
    for  $arrayref   {...};  # loop body executed one or three times?
