I'm not sure I understand: can you elaborate what you mean by that?

>From my POV, the names are quite self-explanatory, and in a production
build these small functions are all inlined by the compiler, so I
don't think I see a significant downside.  (There _was_ a downside in
the past: the annoying job of converting all direct accesses to struct
members to function calls, but that's water under the bridge.)
