The AST generated by SmaCC has a postCopy in the same way that you describe, so I'd say this is OK.
That's good
Just be precise about what you copy and what you don't copy. Can you say what will be copied and what won't?
For instance, in RBMethodNode I want to copy replacements inst var. Another example: for RBReturnNode - return and value inst vars.
