Hello,
I wrote the following split function for Strings:
splitS :: String -> String -> [String]
splitS a b = splitA a b
where
z = length b - 1
splitA [] _ = [""]
splitA (c:cs) (d:ds) | c == d && fst s == ds = "" : splitA (snd s) b
| otherwise = (c : head r) : tail r
where
r = splitA cs b
s = splitAt z cs
example: splitS "Test;Hello;+123.5;+ 7" ";+" -> ["Test;Hallo","123.5"," 7"]
How could it be optimized on speed?
Does there exist already an optimized split for the conventional String type?

Thanks in advance for your answer.
h.
