Another way is to look into the package symbol table. For example: 
use strict;
use warnings;

use Devel::Symdump;

use CGI; # for our example we will look into the CGI package

my $obj = Devel::Symdump->rnew( 'CGI' );

my @f = $obj->functions;

print join "\n", @f;

And here part of the output: 
CGI::Util::rearrange
CGI::Util::make_attributes
CGI::Util::utf8_chr
CGI::Util::simple_escape
CGI::Util::unescape
...
CGI::croak
CGI::import
CGI::binmode
CGI::self_or_CGI
CGI::expires
