I'm surprised that Solidity doesn't recognize that the previous i++ version was already bound by i < packContent.tokenAddresses.length and cannot overflow :)
Feels like Solidity could do this optimization by itself?

Haha. Yes, it does in some scenarios. This change saved a bit of gas so I guess this isn't one of them.
Usually I wouldn't bother with it but we are so close to the bytecode limit for this contract that it's worth including.

Adds ERC1155Holder, which accepts ERC1155 tokens and allows them to be claimed by the claimant encoded in the data.
This prevents the user from denying certain tokens when interacting with
packs.reveal(), which would allow them to retry for a better reveal.Includes some trivial optimizations to keep bytecode size within the limits.
This change does not require any ABI updates.
This includes NC-03, flipping the
_commitmentnested mapping keys.Future optimizations if we can reduce bytecode size further:
