Compiler Error

  1. By using extended delimiters for string literals, all special characters including the backslash will be represented as normal characters.

  2. Not limited to optionals, any type can conform to ExpressibleByNilLiteral to have a special initializer called if nil is used along with that type.

  3. Like integer literals, floating point literals can be expressed in binary, octal, decimal, or hexadecimal forms.

  4. Although Dictionaries prohibit it, ExpressibleByDictionaryLiteral allows for multiple entries with the same key.
