Hi
I've written a function that checks for a substring in a given string. 
This seems like a common thing to do and was wondering if there is a 
function that does this in one of the standard modules.
stringContains :: String -> String -> Bool
stringContains _ [] = True
stringContains [] _ = False
stringContains (h:t) (h1:t1) = if h == h1 then stringContains t t1 else 
stringContains t (h1:t1)
Do you intend the following behavior?
*Main> "x.y.z" `stringContains` "xyz"
True
Nope
