I wrote this when I was cleaning up array(). The use case for it is
that, in generic code, you generally assume that calling array() on a
range will result in you receiving a random access range. This makes
that assumption valid even for narrow strings. In other words, it
eliminates an ugly special case.

I'm seeing a recently-added overload of array() that spells:
==========
ElementType!(String)[] array(String)(String str);
Convert a narrow string to an array type that fully supports
random access. This is handled as a special case and always returns a
dchar[], const(dchar)[], or immutable(dchar)[] depending on the
constness of the input.
==========
What are some good use cases for it?
