Hi Andreas:

Could you elaborate a little on this change?

I thought the idea was that the cloned AST trees can specialize themselves completely independently. Also with regard to the types in the frames. So, in TruffleSOM I am also making sure to clone the frame slots properly and clone all lexically embedded methods to have a proper match of descriptors and slot objects.

Is all this not necessary anymore?

Best regards
Stefan
