Revert r44119 "Remove extract() comment"

extract() is pretty much the devil and shouldn't ever be used for safe, legible code because it makes it much more difficult to analyse the code -- you have to run around trying to track down the source of local variables and there's generally a lot of pain.
Removing the FIXME comment isn't a substitute for fixing it. ;)
