It's the typo. Note that you'll also need an Eq a typeclass constraint for
this type signature to be correct (which is the next error you'd get)

I have this
intersect1 :: ([a],[a]) -> [a] intersect1 (s,[]) = [] interesct1 (s,t:ts) | elem t s = t : intersect1 (s,ts) | otherwise = intersect1 (s,ts)
and when I try this
intersect1 ([1,2],[1,2,3])
I get the error
Non-exhaustive patterns in function intersect1
Not sure what's wrong with this.
