Discussion: Add safeWithFile function

[John Lato]

I would support adding this function under the name `withFile`, in a new
module exported by the deepseq package, as Henning seems to be suggesting.
I don't think it's particularly important, but this pattern arises often
enough that I think it's worthwhile.
