Try (define (a:a)) instead of (define a:a) if you want to define the default functor; the functor is a function. If you truly want to define a:a (not the default functor), then... yes, what is the right result.
By the way, I get this result:
newLISP v.10.6.2 64-bit on Linux IPv4/6 UTF-8 libffi, options: newlisp -h
