A sample code :

module a.main;

class A {
    A[] a;
}

class B {
    A foo(A a) {
        return a;
    }
}

import std.algorithm;
import std.array;

auto bar(A a) {
    auto b = new B;
a.a.map!(s => b.foo(s)).array;
}

void main() {
    auto a1 = new A;
    auto a2 = new A;

    a1.a = [a2];

    bar(a1);
}

module b.b;

import std.string;

Linking both is important, as well as importing std.string . The usage of map
require the delegate to be templated one.

Seems to be the same as 8854 and 8832.

Would someone care to throw this at dustmite to reduce it?  A smaller test case
will be required for the test suite and would help make it easier to debug.

Filed new 8899 because the topic is large and summarizes information from other
issues. Hope it helps.
