class `Lexer`;
  pure nothrow this(const(char)* `filename`, const(char)* `base`, size_t `begoffset`, size_t `endoffset`, bool `doDocComment`, bool `commentToken`);
    Creates a Lexer for the source code base[begoffset..endoffset+1]. The last character, base[endoffset], must be null (0) or EOF (0x1A).
    Parameters:

    const(char)* `filename` | used for error messages
    const(char)* `base` | source code, must be terminated by a null (0) or EOF (0x1A) character
    size_t `begoffset` | starting offset into base[]
    size_t `endoffset` | the last offset to read into base[]
    bool `doDocComment` | handle documentation comments
    bool `commentToken` | comments become TOK.comment's

  pure nothrow @safe Token* `allocateToken`();
    Returns:
    a newly allocated Token.
  final nothrow TOK `peekNext`();
    Look ahead at next token's value.
  final nothrow TOK `peekNext2`();
    Look 2 tokens ahead at value.
  final nothrow void `scan`(Token* `t`);
    Turn next token in buffer into a token.
  final nothrow Token* `peekPastParen`(Token* `tk`);
    tk is on the opening (. Look ahead and return token that is past the closing ).
  static pure nothrow const(char)* `combineComments`(const(char)[] `c1`, const(char)[] `c2`, bool `newParagraph`);
