These are all worth thing to do, but there are two different type of
operations here - those that operate on filenames, and those that do
IO. As Simon Marlow has previously said, keeping these things
separate is usually a good idea.
This also seems to be an attempt to replace type FileName = -
something that is going to take much more work.
Rolling my FilePath code into this package is perfectly fine, but I
think the FilePath operations specialised to String (as defined by
Haskell 98) are important to go into base, if for no other reason than
without them Cabal cannot depend on them.
I realise you are trying to split up the base library, but Cabal
requires it keep to be kept intact just a little bit longer ;)
