As I said, I used veryDeepCopy for copying ASTs, and it worked. But! It takes time to copy:)

You see, when I alpply deepCopy instead of copy, pharo image doesn't respond:)
What I want is to get 100% independent new object ast2, with same caracteristics as ast1.
P.S. Uko, thanks veryDeepCopy works. Read the comments to both methods but still confused why deepCopy didn't work.
