Btw, if you replace this with 'test[0] = test;' it works as expected.
The postblit ctor and the assignment operator get called and the dtor
is called twice.
It looks like the rt is not calling the postblit constructor when
concatenating arrays. For example, the following code:
import std.stdio;
struct Test
{
this(this) { writeln("copy done"); }
void opAssign(Test rhs) { writeln("assignment done"); }
~this() { writeln("destructor called"); }

I think Don has said this wasn't fully his idea. The D community is good at

I think this is not yet possible. I am not sure, but maybe even small changes

I'm new to D and trying to follow Alexandrescu's TDPL code examples I came

Ok, I think I get it. That cleared it up. =).
So, if you have a functioned labelled pure, it's your job to not pass it
mutable arguments, but the compiler's job to
make sure it doesn't mutate anything not in the arguments. And that's why a
strongly pure function can call a weakly
pure one - only
