If a lambda function uses a local variable, that variable is captured using a hidden this-pointer. But this capturing is always by reference. Example:

    int i = 1;
    auto dg = (){ writefln("%s", i); };
    i = 2;
    dg(); // prints '2'

Is there a way to make the delegate "capture by value" so that the call prints '1'?

Note that in C++, both variants are available using
   [&]() { printf("%d", i); }
   [=]() { printf("%d", i); }

No currently there is not.
