+  The name is a C++11 user defined literal operator.  User defined

 ``DeclarationName``\ s are cheap to create, copy, and compare.  They require
 only a single pointer's worth of storage in the common cases (identifiers,
 zero- and one-argument Objective-C selectors) and use dense, uniqued storage
