Is is possible to 'disable' .init for a struct?
source/app.d
```
import std.stdio;
void main()
{
// Can still create Archive with an empty filename. We can't
have that.
auto noDefault = Archive.init;
writefln("fileName: [%s]", noDefault.fileName);
}
// adding a constructor automatically removes default
constructor, so need to disable it.
struct Archive
{
string fileName;
@disable this(); //
Cannot call default constructor
@disable this(ref const(typeof(this))); // Disable the copy
constructor
@disable this(this); // Disable the postblit. Always do
this.
@disable typeof(this) opAssign(ref const(typeof(this))); //
Disable assignment operator
this(string fileName) { // Explicit constructor, can be called.
this.fileName = fileName;
}
}
```
Console output:
```
fileName: []
```
