Description:
symbols-only hash for Ruby
SymbolTable is a handy little Ruby class that was conceived from the union of Hash and Symbol. SymbolTable directly extends Hash, but it stores all keys internally as symbols. Any key that cannot be converted to a Symbol is not valid. . While this may seem restrictive, it does have the nice side effect of making all keys slightly more memorable and usable. For example, values may be set and retrieved using any key that resolves to the same symbol.
