import std.array: array;
struct Foo1 {
    int i;
}
struct Foo2 {
    immutable int i;
}
void main() {
    enum r1 = [Foo1(1)].array; // OK
    enum r2 = [Foo2(1)].array; // Error
}


dmd 2.066alpha gives:

...\dmd2\src\phobos\std\conv.d(3908,23): Error: memcpy cannot be interpreted at
compile time, because it has no available source code
...\dmd2\src\phobos\std\array.d(45,23):        called from here:
emplaceRef(result[i], e)
temp.d(10,24):        called from here: array([Foo2(1)])
