Yes. For the sake of completeness, any expression needed at

That should mean "may find interesting". And I've just realized that the
chapter link is off in that video. This is the beginning of that section:

Yes. For the sake of completeness, any expression needed at compile time
will be (attempted to be) executed at compile time. For example,

yes, D guarentees this at 100%.

in such a manner. And my question was, why a specific array
behaves not as expected.
So, either there is a problem with filling an array, or, there
is a problem with implicit conversion of a Nullable!T to its
underlying type.
Learned something new. I guess I missed that detail when I read
that page.

Nicer than a cast: construct a Nullable!int.
arr[] = Nullable!uint(1);
ok... so... this makes the error very strange, then... almost
senseless...

I thought this was supposed to halt with an error rather than
compile and set all members to 1.
The syntax, to me anyways, doesn't really communicate the
intention of: set all members to 1.

Hi,
I would like to pre-create a double array, each element is calculated by
a function.
//-

import std.conv;
import std.string;
template f(int N)
{
bool fn(double[] tb)

static double[N] dd = void;
dd is not a compile-time constant.
static auto tmp = f!(N).fn(dd);
The initializer of tmp must be a compile-time constant, but since dd is
not a compile-time constant, you can't use CTFE on fn.
