Sure, it's just that in this case the reference code (igraph) is _much_ more
performant. I'm keen to try and identify the major i

Allocate a buffer somewhere, on the stack or heap, and then
instead of using a map()+array() as in that code use map()+copy()
plus a test to be sure the space is sufficient.
But in the end I don't know how much well even ldc2 will comp

Sometimes you can keep memory allocation low, performance
almost acceptable, and code easy to read using a pre-allocated

For your benchmarks are you using the ldc2 compiler with correct

BTW, when I use mixin in my code, the error goes away but no
pragma msg is produced, so it is not a solution.

I have quite complicated data structure (class-based) and I need a copy of
it in a Task (std.parallelism). There is a simplification of data structure
and my program:
class A {
B [] arr;
}
class B {
C c;
}
class C {
A a;
}
void main () {
a = new A();
