When can't you call $x->can('foo') safely? When $x can't can(), of course! 
for $x ('main', undef, \1) {

  if (UNIVERSAL::can($x, 'can')) {

    # ok

    print "can can\n";
    $x->can('foo');
    print "\n";

  } else {

    # error: Can't call method "can" on undefined value/unblessed refe
+rence ...

    print "can't can\n";
    eval { $x->can('foo') };
    print "$@\n";

  }

}
