#define TD_ALLOW_UNDEFINED_WORDIDS 0
// if 1, word ids that are >= end() will give a numeric token name (single per-thread shared buffer), which of course won't be Convert-able back to the id, because it's not added to the dict. This is a convenience for logging fake token indices. Any tokens actually added to the dict may cause end() to overlap the range of fake ids you were using - that's up to you to prevent.
