How is 'strict' used with modules that that create variable such as Env and maybe Opt? 
use Env;
use strict;

if ( defined $SHELL) {
        print "$SHELL\n";
}
root@whitebox:/tmp# perl testEnv.pl
/bin/bash

With the 'if' clause in the code, all is well as long as there is such an environment value. But if the possible value isn't in the environment (e.g. EGGSHELL is not defined): 
use Env;
use strict;

if ( defined $EGGSHELL) {
        print "$EGGSHELL\n";
}

root@whitebox:/tmp# perl testEnv.pl
Global symbol "$EGGSHELL" requires explicit package name at testEnv.pl
+ line 4.
Execution of testEnv.pl aborted due to compilation errors.

What is the correct explicit package, and if Env, what is the correct syntax?
