Hmm, I didn't know that syntax was legal. But apparently it's some form
of typesafe variadic function [1]. It also work for built-in types:

foo(3);
foo(3, 4); // error, too many arguments
}
Not sure what the purpose of the latter is.

I believe it probably calls the builtin constructor:
auto i = int(3);
auto i = int(3, 4); // error
Indeed it seems useless to have such a thing, as most builtin ctors
would be equivalent to passing a convertible value anyway.
