When I create a function that uses wildcards and then compile, it returns an error informing me that the types are undetermined and to request to connect something to it. If I ignore this, and then use the function anyways, it defaults the input types to integers rather than being wildcards.
A good example is to create a new function, add a Set Array Elem inside of it, then drag the Inputs from the Set Array Elem to the Input area of the function so that it auto-creates the pins. If you then compile, the compiler will give an error.
If anyone needs the reason for doing this, I am trying to increment the index integer along with setting the array element.
