I'm also having that trouble. It's something that is much easier to 
understand in Perl5, as there is no Proc/Block/Method difference and 
lambdas always work the same and so do breaks.

sub myiterator { my($list,$proc)=@_;
  for my $i (@$list) {
    $proc->($i)
  }
}

sub func {
  my($x)=@_; print "$x\n"; last; print "after\n"
}

my $lambda = sub { my($x)=@_; print "$x\n"; last; print "after\n" };

myiterator([1..10],sub {my($x)=@_; print "$x\n"; last; print "after\n"});
myiterator([1..10],$lambda);
myiterator([1..10],\&func);

------------------8<--------cut-here--------8<------------------
prints this:

1
1
1

perl is so easy. sometimes.
