It "works" fine for me:
use warnings;
use strict;
use Data::Dumper;
my %d = map { $_, \&{'create_' . $_} } qw(first);
print Dumper \%d;
$d{first}->();
sub create_first {
print "first!\n";
}
Output:
$VAR1 = {
'first' => sub { "DUMMY" }
};
first!
...so you need to describe what's not working as expected.
Are you wanting to call the sub like this?:
$dispatch{_create_first}->();
If so, you need to map the '_create_' to both arguments to map. This example uses a second map() to modify the $_ variable on the way into the map that creates the actual dispatch table.
use warnings;
use strict;
use Data::Dumper;
my %d = map { $_, \&{$_} } map {'create_' . $_} qw(first);
print Dumper \%d;
$d{create_first}->();
sub create_first {
print "first!\n";
}
Output:
$VAR1 = {
'create_first' => sub { "DUMMY" }
};
first!

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).
