Please consider adding support for --exclude @<any set>

Alternatively an expansion script could be included in some form
into app-portage/gentoolkit or app-portage/portage-utils

Like for example:

--- genexclude script ---
#!/bin/bash
[ "" = "$1" ] \
  &&echo "$0 Error: Must have SET name as arg for '--exclude=cat/pkg'" 1>&2 \
  &&exit 1
e=""
while [ -f /etc/portage/sets/$1 ] ; do
   while read a rest ; do
      a="${a%%#*}"
      # empty comment line
      [ "" = "${a}" ] &&continue
      e="$e --exclude=$a"
   done </etc/portage/sets/$1
   shift
done
echo -n "$e"
--- end script

Then this command works: emerge $(genexclude mysetname) -au @world
