We can almost do this with GNU date, GNU mailutils frm.

for i in `searchmsg --header=Subject "matching string"`
do
 # mailutils frm does not take argument to print a single message .. yet.
 ## datehdr=`frm --field=Date $i`
 # so we cope with grep/sed.
 datehdr=`frm --field=Date -n |grep -E "^$i" | sed -e "s/^$i//"`
 datehdr=`date --date $datehdr +%Y.%m%d`

 d=1
 max=`msgproperties --print-attachment-count $i`
 while [ $d -ne $max ];
 do
   readmsg $i > $datehdr
   d=`exprt $i + 1`
 done
done

Na .. sure it will be slower.

Or provide lots of small utilities that can do specialize tasks
and glue them with the shell.

Remember MH (Mail Handler).  One thing on my todo list is to port it.

I choose ... java.

"a little"
un peu.

"mostly"
la plupart du temps.

You just have to remember one, "oui".  And one onomatopoeia
"ooh la la" ..

I remember in interview Bjarne Stroustrup, saying the same thing
not the same manner though, he was using the Java classes/packages
as an example.

If it still raining on your side of the world(it is here)
I'm working on inetutils.  The idea is to break it into
small libs that can be quickly use. For example,
ftp --> libftp.a
tftp --> libtftp.a
etc ..

Interresting.
