There are various ways to avoid this problem, using static classes/structs is one of the simplest:

void main() {
    static class B {
        int a;
        this(int aa) { a = aa; }
    }
    auto foo = {
        return new B(1);
    };
}

The error message is confusing, though. main is not a nested function, rather it's a function _containing_ a nested class...

If you don't like the error message then I suggest to open in Bugzilla a diagnostic bug report (if you want with "minor" importance).

It's a compiler bug.
