This is a bug report for perl from abigail@abigail.nl,
generated with the help of perlbug 1.34 running under perl v5.8.0.


-----------------------------------------------------------------
[Please enter your report here]

    #!/usr/bin/perl

    use strict;
    use warnings;

    my @foo = qw /one two three/;
    sub foo () : lvalue {@foo}

    print for foo;
    __END__
    Use of uninitialized value in print at /tmp/bug line 9.


However, I expect it to print "onetwothree" (which is does in 5.6.0).
If I remove the ': lvalue', or change the print statement to
'print for my @a = foo', it prints "onetwothree".

This bug occurs from 5.6.1 up to and including bleadperl.
