either the $k or the $closure method work

Be careful! Whilst the for my $name... works, it is dangerous:

my @names = qw[ the quick brown fox ]; undef %h; for my $alias ( @names ){ $h{ $alias } = sub { print $alias; $alias = 'fred'; ####### Mysterious action at a distance +here }; }; pp \%h; { brown => sub { "???" }, fox => sub { "???" }, quick => sub { "???" }, the => sub { "???" }, } for my $key ( keys %h ) { $h{ $key }->(); };; the fox brown quick print @names;; fred fred fred fred

With the for my $name ( ... ) method, the closures are and remain aliases to the source list in the for loop; which means that if you assign to the closure within the subroutine, you will cause spooky action at a distance to the content of that source.

And perhaps worse, changes to the source of the for list, will remotely change the contents of the closures:

[0]{} Perl> my @names = qw[ the quick brown fox ]; undef %h; for my $alias ( @names ){ $h{ $alias } = sub { print $alias; }; }; pp \%h; { brown => sub { "???" }, fox => sub { "???" }, quick => sub { "???" }, the => sub { "???" }, } $names[ 1 ] .= 'Mysterious changes'; ###### And again here! for my $key ( keys %h ) { $h{ $key }->(); };; the fox brown quickMysterious changes

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
