Another expression based language is Algol 68.  Not only is

a := case month
       in 31, if year mod 4 = 0 then 29 else 28 fi, 31, 30, 31, 30, 31, 31,
       30, 31, 30, 31 esac;
legal, but so is

if a=b then a else c fi := d;

and they can be abbreviated to
a := (month|31, (year mod 4 = 0|29|28), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);

and
(a=b|a|c) := d;
respectively.  (And who said C could be terse and unreadable?)
