Try this. Not sure how it stacks up for speed, though. (As others have
suggested, if 'for' loop is giving you speed heartburn, use a list
comprehension.)
In this case, splitUsing is called only once, to create the embedded
function tmp. tmp is the function that split will call once per list item,
using whatever characters were specified in the call to splitUsing.
