Setting environment variables after perl has started up cannot affect
how perl starts up (but will effect any other Perl programs you run
with some variant of [exec][0] after that point). If you want to
modify @INC at compile time, you should use the lib pragma.
Now for the pure silliness's sake, you could always say
#!/usr/bin/perl
use strict;
use warnings;
#warning, don't do this, use lib instead
$ENV{PERL5LIB} = "/opt";
#if /opt isn't in @INC re-execute the program with the changed env
exec $^X, $0, @ARGV unless grep { $_ eq "/opt" } @INC;
print "$_\n" for @INC;
