The classes in Foo and Bar (typically just 1 class in each file) can reference the each other without requiring an import statement. This is a change to previous functionality where Foo would have to import Bar in order to reference it with the statement "self import: 'st.redline.Bar'."
We think not having to do this for classes in the same package is easier and nicer.
Where the class you want to reference is NOT in the same package an import statement is still required.
Note: You don't have to import the classes in the Redline core package as this is also done for you by the compiler.
The above changes are in github head and will be in 0.4-SNAPSHOT when pushed to the Maven Sonotype repo.
