You're right!

That makes things even more curious then. I had noticed the problem in some more complex code
and just assumed it would be the same in the simple code that I presented.

That said, I have managed to create a slightly more complex example that *does* break.

import std.algorithm: map, equal;
import std.range: iota;
import std.stdio;

struct Bar
{
    float[1] m;
    this(float a) { m = [a]; }
}

class Foo {
    Bar[1] m;
    this(Bar a) { m = [a]; }
    const foo(int i) { return m[i]; }

    const allFoo1() {
        auto fun = (int i) { return foo(i); };
        return map!(fun)(iota(m.length));
    }

    const allFoo2() {
        return map!((int i){ return foo(i); })(iota(m.length));
    }
}

void main()
{
    Foo f = new Foo(Bar(1));
    assert(equal(f.allFoo1(), [Bar(1)]));
    assert(equal(f.allFoo2(), [Bar(1)]));
}
