Tests a case where concrete abilities were appearing multiple times in an inferred type. This was due to the pre-pass that figures out which abilities are being matched on. It was just concatenating the ability for each pattern into a list, and not checking whether there were duplicates.
structural ability T where
nat : Nat
int : Int
flo : Float
f = cases
{nat -> k} -> 5
{int -> k} -> 5
{flo -> k} -> 5
{x} -> 5
