Oh, sorry, yes I get what you're referring to.

What I was wondering is if we could assign the numbering later, once the type is being committed (when we're copying the accelerator table entries over from the temporary table to the main table & switching from DIE pointers to offsets - at that point we know the type units are real, and we could assign numbering there instead? (like the order/index of the entry in the TUSymbols list))
