Running my code on AS 2.28.1 WIP (taken from svn 2013-11-20)

Following code gives an error "ERR : Identifier 'Parent' is not a data type"

class Parent {}
namespace child {
   class Child : Parent {}
}

but 2nd code compiles without any errors

class Parent {}
namespace child {
   class Child : ::Parent {}
}

Will the scope operator "::" be mandatory also in future?

The compiler should be able to search the parent namespaces for symbols already. I implemented this in version 2.26.3 (released in May).

I believe you've stumbled upon a bug in the code. I'll investigate it and have it fixed as soon as possible.

I've fixed this bug in revision 1793.

Thanks,

Andreas
