Include constant in pod

Is it possible to include the contents of a constant in the POD for a module. Example:

use constant DEFAULT_URL => "http://www.example.com";
...
=item B<setUr开发者_StackOverflowl>

Change the URL to query. Default is [contents of DEFAULT_URL here]

=cut

According to this link, no this is not possible without some work. You could write another script to generate the POD documentation, and that could include the variable.
