as far as safety aspects are concerned, you might consider adding
yourself to http://hackage.haskell.org/trac/ghc/ticket/1380 ?

although i understand that you also want checking for overflow
in otherwise unrestricted programs, which would be a separate
issue/ticket.

if you have anything beyond unsafe foreign libs, or invalid indexing
in mind, could you add it to that ticket, please? and perhaps to

http://haskell.org/haskellwiki/Safely_running_untrusted_Haskell_code

which concerns lessons learned about guarding lambdabot 
against exploits? lambdabot has been boldly going where no
one has gone before for quite a while now, but that doesn't
ensure that all holes have been plugged.
