( #3333=superdoc: print w/replies, xml ) Need Help??

Or you could do it functionally rather than explicit recursion using List::Util's reduce (not that that's likely to be of any help to trolls who're unfamiliar with a bog simple recursive sub . . .).

## (reduce #(hash-map %2 %1) 1 (reverse [:foo :bar :baz :quux])) use List::Util qw( reduce ); use Data::Dumper qw( Dumper ); my $hash = reduce { +{ $b => $a } } 1, reverse( qw( foo bar baz quux ) + ); say Dumper( $hash ); __END__ $VAR1 = { 'foo' => { 'bar' => { 'baz' => { 'quux' => '1' } } } };

The cake is a lie.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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 or How to display code and escape characters are good places to start.
