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

final nothrow void scan(Token* t);

Turn next token in buffer into a token.

final nothrow Token* peekPastParen(Token* tk);
