The default initializer can easily be disabled:

@disable void[0] init;
@disable this(this);

Now nobody can do
auto x = S.init;
@disable void[0] init; Sound hacky as hell. Is it made by design, or is
it a consequence of the current compiler implementation ?
Built-in properties can be hidden (I am almost sure it is by design),
void[0] just means 'field with size 0' and is explicitly allowed by the
language specification. @disable is by design as well. I orthogonally
combined those three features in order to disable the built-in .init
property.
But it is still possible to do:
S[1] x;
I'd have expected that to fail with disabled this(). Is this a bug?
Yes.

It make much more sense that way. At least we can prevent us from
getting garbage struct when it comes to interface with C++.
