I have a struct where I need to perform default initialization

Are there any patterns or idioms I could use to get the desired
result? Or is it just the case if I use a constructor I have to
pass values to it?
struct Foo(T)
{
private int _bar = 1;
this(int bar)
{
this._bar = bar;
}
}
auto foo = Foo!(string)();
This should do the trick.
