That _sounds_ nice, but consider this:

version (linux) {
     import core.sys.linux.dlfcn;
}
else version (FreeBSD) {
     import core.sys.freebsd.dlfcn;
}

version(linux || FreeBSD) {
     dlopen(...)
}

I shouldn't have to add another version just for that last dlopen block.  
It's not "finegrained" control, it's cruft.
