This comes up a lot. 

I thought at some time last year there'd been a long discussion about
all the various flavours of 'split' that we could come up with. But
then, what happened to the code? Did we not agree on a version to go
into Data.List?

Hacking up your own custom split (or a tokens/splitOnGlue) must be one
of the most common questions from beginners on the irc channel.

Even fps has a split/splitBy:

    http://www.cse.unsw.edu.au/~dons/fps/Data-ByteString.html#v%3AsplitWith
    http://www.cse.unsw.edu.au/~dons/fps/Data-ByteString.html#v%3Ajoin

Anyone rememeber what the result of the "let's get split into the base
library" movement's work was?
