For Perl programs:
- Most of the C guidelines above apply.
We nowadays have a proper mishmash of struct-related functions that are called `<verb>_<struct>` (e.g. `clear_prio_queue()`) versus functions that are called `<struct>_<verb>` (e.g. `strbuf_clear()`). While the former style may be easier to tie into a spoken conversation, most of our communication happens in text anyway. Furthermore, prefixing functions with the name of the structure they operate on makes it way easier to group them together, see which functions are related, and will also help folks who are using code completion. Let's thus settle on one style, namely the one where functions start with the name of the structure they operate on.
