I might attempt this like this, which is a little more verbose than the string version of eval, but "feels" more correct to me (though there's nothing wrong with using that other form of eval): 
BEGIN {
  eval {
     require Time::HiRes;
     import  Time::HiRes 'time';
  }

  warn "Couldn't load Time::HiRes, but that's OK\n\t$@"
     if $@;
}
