[Pharo-users] [Oharo-users] Copy AST

[Mark Rizun]

Hi everyone,

I want to get a deep copy of ast. But deepCopy doesn't work:)
What I mean:

| ast1 ast2 |
ast1 := RBParser parseRewriteExpression: 'self'.
ast2 := ast1 copy."or without copy"
ast1 stop: 99.
ast2 stop

When evaluate this you get 99. I want it to be 4.
So I want to have separate object ast2 with separate data, not depending on
changes made in ast1.
As I said deepCopy doesn't work. Any ideas?

Thanks,
Mark
