You skipped the most interesting case - what to do when the list is *almost* long enough to accommodate all of the non-rest params. `let [a = 1, b = 2, ...rest, c = 4, d = 5] = [9, 8, 7];` It seems, from your second test case, that a=9 and b=8, but which variables gets a value of 7 - c or d? ~TJ _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
