One or the other should be changed so that these agree:

although I couldn't say which is "right" OTTOMH...

I hadn't noticed. In my opinion the Data.List version is more consistent,

split 'a' "xx" == ["xx"] split 'a' "x" == ["x"] split 'a' "" == [""]

and

split 'a' "aa" == ["","",""] split 'a' "a" == ["",""] split 'a' "" == [""]

Versus:

B.split 'a' "xx" == ["xx"] B.split 'a' "x" == ["x"] B.split 'a' "" == [] B.split 'a' "aa" == ["","",""] B.split 'a' "a" == ["",""] B.split 'a' "" == []
