Now compiling this code:

struct Foo {
    this(int) nothrow { // line 2
        throw new Exception("something");
    }
}
void main() {
    Foo(1);
}


It gives:

temp.d(3): Error: object.Exception is thrown but not caught
temp.d(2): Warning: statement is not reachable
temp.d(2): Error: constructor temp.Foo.this 'this' is nothrow yet may throw
