it didn't occur to me that i didn't have to use a typeglob as my holder. good idea, and although it's a core module, this approach means i have one less use statement. Can anybody tell me why do this:

if    ($type eq 'SCALAR') { undef ${*{$glob}} ;}
  elsif ($type eq 'ARRAY')  { undef @{*{$glob}} ;}
  elsif ($type eq 'HASH')   { undef %{*{$glob}} ;}
  elsif ($type eq 'CODE')   { undef &{*{$glob}} ;}
  elsif ($type eq 'IO')     { close *{$glob} ;}

instead of this:

($type eq 'IO') ? close *{$glob} : undef *{$glob}{$type};
[download]

and i have to wonder if just using this would not work:

undef *{$glob}{$type};
[download]

update: I should note that completely eradicating the sub from memory isn't necessarily the problem here, as sometimes the created CODE glob is simply an alias from another package rather than a brand new anonymous sub.

• 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).
