What did you do?

auto complete a function where type params can likely be inferred (e.g. slices.Clone)

What did you see happen?

it auto completes to slices.Clone[|]()

What did you expect to see?

it auto complete to slices.Clone(|) since the type parameter information can almost always be inferred from the function argument(s).
