Not that that's happened so far that I can remember, but it could. I'm 90% sure it's legal to alias `struct {char c;}` pointers with `char` pointers. This specific typedef gives type safety but with a simple one-way `internstr -> const char *` typecast (with `&istr->c`). Converting the other way around is more intentional: a straight up cast `(internstr)cstr` which sticks out as unchecked and probably wrong, or calling the intern(cstr) function, which is the right way. move intern() to mem.c 2025-12-15T20:46:24+00:00 lemon lsof@mailbox.org 2025-12-15T20:46:24+00:00 urn:sha1:c6c0f2ef35175075e91169113cfe856f29b3eb9a Being in lex.c was vestigial, since it was being used all over the frontend and backend. lexer: use a hashmap to lookup keywords 2025-12-15T16:16:41+00:00 lemon lsof@mailbox.org 2025-12-15T11:01:12+00:00 urn:sha1:cb83b9e05b4a704cc6127e087917a87af8c97be1 lex: use pmap for macro lookup 2025-12-12T09:21:43+00:00 lemon lsof@mailbox.org 2025-12-12T09:20:39+00:00 urn:sha1:5f0793c34c4f10a2221b793316fdc82c50d10452 To reduce hashmap code repetition.
