Here "with conversion" means that it needs template argument inference, right?

But this one is not an exact match. It involves an `alias this` conversion from
Nullable!int to int.

As far as I can tell, it should be:
  "match with conversion for initial template arguments"
  "match with conversion for inferred template arguments"

Or maybe just "match with conversion" since there are no template parameters.
The empty template parentheses can actually be omitted without changing the
behavior of the code.
