--- Comment #1 from Basile-z <b2.temp@gmx.com> ---
sorry, test case should be

---
struct Foo
{
    static opCall(T)(T t){}
}

void main()
{
    Foo(0);         //OK
    const(Foo)(0);  //NG
}

--- Comment #2 from Basile-z <b2.temp@gmx.com> ---
in https://dlang.org/spec/expression.html#primary_expressions this is the rule

  TypeCtor ( Type ) ( ArgumentListopt )

The parser takes the path of a declaration, it nevers tries a statement, in this case ExpressionStatement.
