Well, kinda. The OP's problem is that CGI.pm is exhausting STDIN, and it's impossible to seek back to the start of STDIN.

The modern interface for Perl web apps is PSGI (implemented by Plack). The equivalent of reading from STDIN in PSGI is to read from $env->{"psgi.input"}. This is a filehandle that is usually seekable (depending on what handler you're using).

package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name
