The POSIX binding I looked at had a single exception,
POSIX_Error and then you were supposed to examine the
errno variable.  Proctalgia, but it's the price you pay
for interfacing to such a primitive system.  Rather than
"roll-your-own" completely, I'd say use POSIX as a thin
binding and provide a thick binding to wrap it in.
