Lisp in Lua? It does not have Lisp syntax and semantics.

Why would one call it 'Lisp' (which stands for 'Lisp Processor), when for example it does not do list processing as in Lisp?

  > (list 1 2 3 4)
  [string "return list(1, 2, 3, 4)"]:1: attempt to call a nil value (global 'list')
  > (append '(1 2 3) '(3 4 5))
  Compile error in '3' unknown:3: cannot call literal value
