gPAL doesn't even seem to be defined for when the argument is larger
than the path's length.  Define *that*, and the answer to gPAL might
fall out automatically.  Unless the answer is "the last point in the
path", in which case we still have a problem.  I'm torn between
throwing and matching whatever answer we give for gBB of an invalid
path, as it kinda "lives" at that point.

gPSAL should probably throw, (2a).
