If you want to input a set using braces, I suggest
(C1) load("l:/set/nset.lisp")$
(C2) matchfix("{","}")$
(C3) "{"([x]) := apply(set,x);
(D3) {[x]} := APPLY(SET, x)
(C4) {a,b,c};
(D4) {a, b, C}
(C5) set(1,2,3);
(D5) {1, 2, 3}
(C6) {u,n,k,k,n,u};
(D6) {k, n, u}
(C7)
Occasionally, I've used {f,g} for Poisson brackets; thus I wasn't eager to
allow sets to be entered this way.
