Access raw calldata in call handler

[dorothy-zbornak]

We have a bit of an unusual use case at 0x where we append metadata to the end of certain calldata, which we extract later in traces for data tracking. It would be pretty useful to us if the raw calldata (not re-encoded) could be accessed from a Call object in a call handler. Is such a thing possible?

We currently expose the raw input to the transaction, but not to each call.

That's good to know, thanks. Unfortunately our calldata often gets executed in deeper frames by other contracts so we still need to figure out how to account for those scenarios.
