This wrong D2 program:
void main() {
struct Foo {
void bar() {}
}
auto foos = new Foo[1]; // line 5
}
At compile time dmd v2.046 prints:
temp.d(5): Error: cannot have array of inner structs Foo
But for D newbies coming from C or C++ can find that error message cryptic.
Using a static struct solves this problem. So a possible error message can be:
temp.d(5): Error: cannot have array of inner structs Foo, you can use a 'static
struct' instead.
This improved error message is not perfect, but it seems better.
(I don't understand why D error messages don't have the ending full stop.)
