ByteString split:
split 'a' "aXaXaXa" == ["","X","X","X",""]
Neil's:

I prefer the ByteString split (i.e. I prefer separator semantics over terminator), also because it's invertible. Some more support: http://www.haskell.org/pipermail/haskell-cafe/2006-July/016649.html
I prefer the ByteString split as well! That should be the one we use.
A minor issue is, that 'split' does always return a non-empty list, which is not expressed by the list type of the result, but it would be nicely expressed by the alternating list type. In some cases it is necessary to handle the first or the last element differently, which requires that there is a first or a last element.
