+/// In general both SymbolA and SymbolB will also have a modifier
+/// analogous to the top-level Kind. Current targets are not expected
+/// to make use of both though. The choice comes down to whether

+///
+/// Note that this class must remain a simple POD value class, because we need
+/// it to live in unions etc.
