Errmm!  Here's a better example, but with the same results:

----------------------------
module test;

void noparens() {
   immutable char[char] aMap;
   char a = 'a';
   immutable char b = 'b';
   aMap[a] = b;
}

void withparens() {
   immutable(char)[char] aMap;
   char a = 'a';
   immutable char b = 'b';
   aMap[a] = b;
}
-----------------------------
