Follow-up Comment #5, bug #42422 (project octave):

It seems to me that the really simple predicate functions should maybe all be
internal C++ functions.  Otherwise, the overhead of the function call kills
performance, and many of these predicates are called when doing argument
checking, so it would probably be good for them to be as fast as possible. 
They are simple functions, so writing and maintaining them in C++ should be
pretty easy.
