Right. But this shows a different limit. I think code like this is accepted in
Clojure:


import std.algorithm: map;
void main() {
    auto keys = [1, 2, 1, 1, 1];
    auto a = [0, 10, 20];
    auto r1 = map!(k => a[k])(keys); // OK
    auto r2 = map!a(keys);           // Error
    auto aa = [1: 10, 2: 20];
    auto r3 = map!(k => aa[k])(keys); // OK
    auto r4 = map!aa(keys);           // Error
}
