If you can find a different way to initalize your sub, you can get rid of the string eval, which is my only objection. 
eval {
    require module1;
    module1->import();
}
*bar = sub { print "Win32\n" };

You may need a forward declaration, as this is untested. Otherwise, that's probably the first thing I'd try. (It's simple.)
