The code below compiled i pre 0.9 versions of nimrod, but now, (using the windows installer on nimrod homepage), the compiler stops with error message 'inheritance only works with non-final objects'

What am I doing wrong? Something I missed?

#------------------------------------------

type

TAnimal=object TCat=object of TAnimal

Try this:
```
type
  TAnimal = object of TObject
  TCat = object of TAnimal
```
Objects which do not inherit from TObject are now by default final.

To introduce a new inheritable base object that does not inherit from TObject you now have to use the 'inheritable' pragma:
```
type
  TAnimal {.inheritable.} = object
```
