I have added support for non-static inner classes through automatically adding 
'this' as the first argument for calls to inner class ctors for now.
Cheers,mg

classNamePattern support: Non-static inner classes - there is something to be 
said for this argument... 

    Passing the outer class' this reference explicitely to the
    non-static inner classes' ctors makes the test green (see below;
    evidently this is not necessary when using the new keyword). Any
    suggestions on how to best adapt the code to achieve this behavior ?

    Here is the Github of the current state of Newify classNamePattern
    support:
