I love the way D does transitive const and immutable but i have a problem when i use const a struct field.
---
struct MyStruct
{
    int a;
    const int b;
}

struct Range
{
    MyStruct front;
    void popFront()
    {
        front = MyStruct(2, 3);
    }

    enum empty = false;
}

This sample doesn't compile.

That's due to the nature of structs - you would be overwriting a const field.

Const fields should probably be avoided since they aren't all that useful. You could instead do a const getter property for it without a corresponding setter, then make the actual data private.
