Well, if you need conditional use at compile time, that's easy enough to
do:

BEGIN {
  if ($^O eq 'MacOS') {
    require Mac::StandardFile;
    import Mac::StandardFile;
  }
}

use Module is documented to be exactly equivalent to

BEGIN { require Module; import Module }

I'm skeptical that anything could be done with use that could not be done
with require/import.
