Sorry I should add that I'm talking about static ctor/dtor of struct.
The bug I see with 2.067-b2 is this:
1. static this() {}
p.p.s. sure, i can see where i'm creating a closure. but i can't see how
that closure got to IR generator, as it is never executes, there is no
need to generate code for it, and it should be removed after checking
`static if` condition.

you shouldn't cast it like that. use `std.array.array` to get the actual
array. like this:
import std.array;
auto y = x.map!(a = exp(a)).array;
the thing is that `map` returns so-called lazy range. lazy ranges

CTFE may run at compile time but it follows the same rules as run time
evaluation (plus some restrictions).
This means, you can't use dynamic values (e.g. function

Your code works perfectly and makes at least some sense to me.
Thank you.
If i understand it correctly:
p.s. faster weak typing solution is definitely possible if you'll narrow
possible type set. but as i said, i'd not recommend to go this way. there
can be dragon in the end.

Hallo!
Is it possible to create arrays which has more then one type,
f. ex. array[0] = 1; array[1] = z; array[2] = new clazz(),
I tried Variant, but it slow down heavily my app.
it is possible. with Variant. ;-)

After a bit of rethinking:
I guess the compiler goes through 2 loops:
the first resolves __traits, the second does ctfe.
That would explain this behavior. a is not present to the compiler

Suppose I have a function defined like so:

Should it be labeled with @property?
Or is @property only for true member functions?
only if you plan to use it like `foo = 5;`. i.e.

You can use it like that anyway.
sure, but i'm talking about style, not about compiler demands.
i.e. exactly like field variable.
struct S{
void delegate() dg;

int main(){
i have that.

struct on the heap: some containers, for example, doing their own memory
