I can confirm it's attempting to be a tiny CL subset. It has function namespace, symbols, simple numerics macros and backquote.
But error detection is non-existent: (ASSOC) crashed it, since it didn't check for arguments even.
It's at best, a Lisp reader, not interpreter, even if it does a few things right:
(mapcar (lambda (x) (+ x x)) (list 1 2 3)) ==> (2 4 6) :-)

No need for speculation, here is the actual article describing this; submitter should have linked it, instead of just the repl
