Compiler doesn't warn or complain about classes in the same package in different source folders

Steps to reproduce:
1. Create a new Flex Web Project and add src/com and a test/com folders
2. Add a class file called MyClass.as to both folders
3. Add a variable of type MyClass to the main application and compile the app

Actual Results:
The app compiles just fine... no warnings no errors and uses the file in the src/com folder and not the one in the test/com folder

Expected Results:
The compiler should at the very least display a warning.

Workaround (if any):
Nada
