mixing digits and letters Per Bothner 17 Jul 2019 22:49 UTC

The draft, as written, doesn't seem to allow  #x789_AB_CD_EF .

Specifically:
> Underscores between letters a-z A-Z that represent digits in a radix higher than 10 (using the standard hexadecimal
> read syntax, or any implementation-defined read syntax).

does not handle underscores between letters and digits.

This needs some word-smithing.

It wouldn't hurt to add an example, as well.
