Subject: [PATCH] Initialize the components of this class.  Otherwise GCC
 thinks that Array may be used uninitialized, since it fails to understand
 that Array is only used when SingleValue is not, and outputs a warning.  It
 also seems generally safer given that the constructor is non-trivial and has
 plenty of early exits.
