There just has to be a way to remove that eval. ;-)

Why do you 'use $module ( \@import_list )'? You don't need to import anything into Alias::Exporter's namespace. So you only need to require it instead. That can pull it out of the eval if you do the required modifications: 

  (my $modname = $module . '.pm') =~ s,::,/,g;
  require $modname;

Next, we want to pull that loop out of the eval. You have the right idea - it pretty much could have been done without the eval already, except that I just removed the importing from the other module. So now we need to point at the code in the desired module explicitly. 
  for my $var (@import_list)
  {
    no strict 'refs';
    *{$package . '::' . $imports{$var}} = *{$module . '::' . $var};
  }

Of course, having gotten rid of the eval, the die isn't needed anymore, either.

A few more variables could make things a bit easier to read. Also, I would use references a bit more. This gives us: 

sub import {
  my $class = shift;
  my @modules = @_;
  my $package = caller();

  for my $module ( keys %modules ) {
    my $imports = $modules{$module};

    # we need to load the module if it doesn't already exist.
    (my $modname = $module . '.pm') =~ s,::,/,g;
    require $modname;

    for my $var (@import_list)
    {
      no strict 'refs';

      my $from = join '::', $module,  $var;
      my $to   = join '::', $package, $imports->{var};

      *{$to} = *{$from};
    }
  }
}

Unfortunately, that's completely untested. And still needs more commenting ;-) Good luck,
