Detailed Description

Token - This structure provides full information about a lexed token. It is not intended to be space efficient, it is intended to return as much information as possible about each returned token. This is expected to be compressed into a smaller form if memory footprint is important.

The parser can create a special "annotation token" representing a stream of tokens that were parsed and semantically resolved, e.g.: "foo::MyClass<int>" can be represented by a single typename annotation token that carries information about the SourceRange of the tokens and the type object.
