This is a test of the order in which Scheme REPLs evaluate constant arguments.  It doesn't necessarily apply when arguments have different levels of complexity, nor does it apply to compiled code.  The test is `((lambda x x) (display "l") (display "t") (display "r"))`.  In some cases, side-effecting procedures other than `display` were used.

Displays `ltr`: Racket, Gauche, Gambit, Chicken, Bigloo, Scheme48/scsh, Kawa, SCM, Vicare, Ypsilon, Mosh, !IronScheme, NexJ, STklos, KSi, !SigScheme, Scheme 9, RScheme, S7, Rep, Schemik, Elk, UMB, Llava, Sizzle, !FemtoLisp, Dfsch, Inlab, Foment

Displays `rtl`: MIT, BDC, XLisp, SXM, Chibi

Unpredictable order: Chez

Undeterminable order (no side effects): Owl Lisp

The following C code was also tested:

{{{
# include <stdio.h>

int yotz(int a, int b, int c) {
  return a + b + c;
}

int main() {
  yotz(printf("l"), printf("t"), printf("r"));
}
}}}
