And really i think the "Classic" lisp way to loop is loop, not recursion. Both, I think (from long ago memories). The "modern" loop macro (which is probably Turing complete like I seem to remember people saying format is :-) is I think a relatively new thing, I overhead a lot of discussion about its design in the early '80s. Although it probably had precursors, mainline Lisp, now Common Lisp, is decidedly multi-paradigm, there were even sops thrown to FORTRAN programmers as I recall, probably back from when there were only a very few computer languages in existence (heck, LISP's first implementation, on a vacuum tube computer, was as FORTRAN subroutines). So overt things like loop are in theory idiomatic as well as recursion.
