I disagree; I think that answer merely hopes for a solution instead of answering the question directly.

use Test::More tests => 2; sub undef_hash { my $ref = shift; undef $ref; } sub assign_hash { my $ref = shift; %$ref = (); } my $hash_one = { qw( foo bar baz quux ) }; undef_hash( $hash_one ); is( keys %$hash_one, 2, 'undef on hash reference should not clear it' ); my $hash_two = { qw( foo bar baz quux ) }; assign_hash( $hash_two ); is( keys %$hash_two, 0, 'assigning empty list to hash reference should clear it' );

Update: Ahh, I misunderstood. Yes, replacing the subcall will probably work.

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 How to display code and escape characters are good places to start.
