Default is actually FALSE- and it's easy to tell what the default is.
Also, `retval` is canonically used as the return value throughout the

Literally, yes. But FALSE means failure. Since that's confusing, we
should actually return FAIL or OK.
No type system is perfect; it will always be important to utilize some
amount of "hungarian notation" so that you can visually tell what is
right and what is wrong, and avoid connecting the proverbial red wire to
the black wire.
That said, imo it is too bad C doesn't have Haskell's "newtype", so that
TRUE/FALSE and FAIL/OK could truly be distinct types.
