DeepSeq

Would it be possible to bring the DeepSeq library into the libraries distributed with GHC? (I think Dean Herington is responsible for it.) Of course it's easy enough to drop it into one's own program (I am just about to do this) but (1) It is fairly common to want to force deeper evaluation. (2) DeepSeq is simple enough to be dropped in the GHC distribution, without it causing much trouble or making it much bigger. (3) At the same time, it is not so simple that it can be reimplemented in a couple of lines.
