> SymbolSourceImpl Contains two key elements: a list of providers; and a map of Symbols. When using SymbolSource, the assumption Tapestry makes is that the name of a Symbol is always known in order to do a Symbol lookup. 
> Why shouldn't these elements in SymbolSourceImpl be exposed since they are immutable?
> private final List<SymbolProvider> providers;
> private final Map<String, String> cache = CollectionFactory.newConcurrentMap();
> Its a disadvantage not having access to a list symbol names, and not being able to query for where the Symbols resides, the lack of these two features limits the usefulness of Symbols in Tapestry.
