People,
I define, for example,
tuple42(_, y, _, _) = y,
setTuple42 (x, _, z, u) y = (x, y, z, u),
mapTuple42 f (x, y, z, u) = (x, f y, z, u).
But it looks natural to have such functions for tuples in the library.
As Haskell-2010 has zip3, zip4 ..., where are the library functions
That would not be economical. Lets just say people never use more than
8-tuple and then try to count how many functions you would need.
The tuple package on Haskell provides a generic interface to
access/manipulate the k'th element of an n-tuple. That should be
sufficient and is not subject to

For me a plain PDF file, say on code.haskell.org or projects.haskell.org

There is System.IO.utf8_bom for that. Of course, then you can't use
readFile; but you can use openFile and hGetContents.
