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).
