i'm against this exactly because i use (and define) it in my program.
freearc was already broken with 6.8 due to introduction of 'forever'
and i don't like it to broke with every new major ghc version (or even
minor one as some purists prefer). i wonder whether noone here write
software that may be compiled by people outside of haskell island?

Best regards,
