I think you should check using the version of Perl that's running. 

if ( exists $Module::CoreList::version{$]}{'Foo::Bar'} ) {
    print "Foo::Bar is core in this version of Perl.\n";
}

This way you don't false positive on something that's core in a version other than the one you have. I haven't used Module::CoreList, however, so I'm not sure.
