Lexer

I’ve just completed a Lexer in order to produce a stream of tokens for the Parser.

There’s some parts of the Dragon Book which I don’t really understand the reasoning. Such as the Lexer adding info to the Symbol Table… why would it do that? It’s the Parsers job to build a syntax-tree, that seems like the correct place to add symbols. The Lexer is complicated enough just producing a stream of tokens.
