That is not what "fold expressions" mean.  Fold expressions are
newly-introduced C++ syntax where you can write:

	bool b = ... && args;

(with a literal "...") and the compiler automatically expands it to
`args[0] && args[1] && args[2]` (assuming args has 3 elements).

Of course, whether or not D ought to have such a thing is up for debate.
My present opinion is that D doesn't need it, because D's compile-time
capabilities are already convenient enough to use without needing
special syntax support from the language.
