Yeah but I should be able to mark it as `@trusted` without
trusting some random bloody

This is so simple. What is D complaining about?
Should this also work with a Template, as shown?
```
import std.stdio;
void main()
{
// auto add(T)(T lhs, T rhs)

Ok, gotcha.
Placement new is @system, but you wanted to use it in an @safe function
iff the constructor to be called is @safe as well.
The reason placement new is @system is because of double-init. It can't
be a safe operation.

In the following from Programming in D, page 483, we use function
keyword.
I expect that the first int in
```
int function(int);
```
represents the return value.
What does the second (int) refer to?
Then there is another example with 'delegate' instead of
'function.
```
import std.stdio;
This works:
```
import std.stdio;
void main()
{
foo();
}
void foo() {
int addMyInts(int lhs, int rhs) {
return lhs + rhs;
}
int doSomething(int delegate(int, int) doer)

You do not want .init?
Fine:
```d
Archive noInit = void;
```

Sorry, I'm having trouble understanding what you're trying to do.

No (and honestly it's bad style to break the constructors)
