I've seen a lexer/parser scheme that encodes the lexer token type along with the token file location information into a u64 integer, something like

    struct Token {
        token_type: u8,
        type_info: u8,
        token_start: u32,    // offset into the source file.
        token_len: u16
    }

It's blazing fast. The lexer/parser can process millions of lines per second. The textual information is included, and the location information is included.
