Actually, it's been a long time I've not merged anything without '-1' ;)
Only new stuff I explicity want in world gets the honor of me omitting
the -1.

e.g. the haskell x509-validation example in my other mail.

Actually, I guess it's more missing stuff in world, but there's some
stuff that definitely does not belong in world, but depclean wants to
remove it. Again, the haskell sample works. Basically, I only have
pandoc installed that uses anything haskell, so any haskell stuff
installed is because pandoc (indirectly) depends on it. And depclean
wants to remove part of that "stack". Ok, I checked again, it does
look more like "all of it"... Ooops. Pandoc is not in world. Let's
see... (emerge -Ok app-text/pandoc)...
$ emerge -p --depclean | grep haskell
it still want's to remove about half the haskell stack (which is only
installed because of pandoc's deps). Well, 32 out of 134 (according to
'eix -Ic dev-haskell/') or so... And I just reinstalled all that stuff
from scratch (removing all of dev-haskell/ plus ghc itself, and start
from scratch with "emerge --pretend --tree app-text/pandoc').
I'd have to test and remove just the haskell stuff that depclean
suggests, and then start testing... It's a fine example, as it's a
single app pulling in quite a bit that depclean or I or both get
confused about[1] ;)
That's what I call "overeager". There's other stuff. Might have missed
having some in @world, but with most stuff I'm rather sure it's pulled
in via deps of stuff in @world.

Sound's familiar ;)

Wow. You don't use much, eh? ;)

[1] Normally I would not install such a large stack because of one
program, e.g. I've masked all stuff mono/sharp etc. but I'm
interested in haskell in itself, so that's ok :)
