punning in GHC?

hi there, i just discovered that GHC does not support punning with the -fglasgow-exts option. is there another flag to turn this on or has it been completely removed? if so could we have it back - i really like the feature (in patterns anyways) and use it (hugs -98 supports it). i don't particularly care that it is not in haskell 98 as i rarely write haskell 98 programs. by the way before posting this i did a search on "punning" through the mailing list archive to see if someone asked this already. i couldnt find anything but it seems that since 1997 there were 7 posts on "punning" and all of them seemed to agree that it was a useful feature, so why was it removed? bye iavor
