yes, there's a huge advantage. do is not a subroutine. it cannot take parameters. just try to do this!
my %dispatch = (
sub_get_files => sub{ # takes one arg
local *DH;
opendir( DH, $_[0] ) or die 'Cannot open ' . $_[0];
return grep { -f $_ } readdir(DH)
},
);
my @files = $dispatch{sub_get_files}->( $dir );
do executes immediately, and would spit the results into the hash. icky.<p

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).
