commit da9c7c6e895765ea55d68bec11904da1cd4d36c6
Author: G. Branden Robinson <[email protected]>
AuthorDate: Sun Nov 9 08:34:56 2025 -0600
[refer]: Slightly refactor (boolify).
* src/preproc/refer/token.h: Declare `get_token` as returning a `bool`
rather than an `int`.
* src/preproc/refer/token.cpp (get_token): Demote return type from `int`
to `bool`. Return Boolean, not integer, literals.
