How does this work if it is given an empty list as a parameter?

I guess if one is always able to construct default values of T then this is not a problem.

this is how go handles it;

  func do_thing(val string) (string, error)

is expected to return `"", errors.New("invalid state")` which... sucks for performance and for actually coding.
