I see. Then a better name might be

DeepSeq.IO.withContents

or

DeepSeq.IO.withFileContents

or

DeepSeq.IO.hWithContents


I still think, that 'safe' is not a good part of a Haskell function name, 
because 'safe' should be the default. If at all, we could rename 
hGetContents to unsafeHGetContents.


A nested call to withContents would still run deepseq twice, right?
