Maybe this is a duplicated error report, but I haven't found it.

Current dmd 2.049 doesn't support nested functions with "auto" return value:

void main() {
    auto foo() {
        return 1;
    }
}


DMD shows:
test.d(2): no identifier for declarator foo
test.d(2): semicolon expected, not '{'


But this is an useful feature to have because "auto" is becoming increasingly
important as lazy Ranges often have a very complex type.
