I like it, with a further note that 'internal' would be more precise: a libc
does not hand off pointers to its internal functions to callers.
(well, 'internal' might be subtly broken in a toolchain due to zero real-world
use, but that's unlikely; it's probably handled exactly like 'hidden', and
does not help optimizers today)
