Hi,

I'm working on chapter 3 exercises, ex 3.39 says we should extend the translator & interpreter to handler `pack` and `unpack`.

I can find the definition of `unpack` in ex 3.18, but I find `pack` nowhere in the book.

I'm wondering what would `pack` do?

Thank you.

Yes, there is no 'pack'.  You can safely ignore that part of exercise 3.39. (Sorry about that.)
