@Evalir regarding this q: foundry-rs/foundry#5574 (comment)

ETA depends on Ethereum core devs and when they finalise Cancun, for example, EIP-4788 got a major change last week.

I decided to drop #536 PR as i need to be mindful of my time and it is safer to just rewrite it, as I got burned with mcopy that took a lot of my time, and in the end, there were multiple consensus issues found after it was merged #528, if you want you can take a stab at it on rewriting it, be free to do it.

Others EIP I would not recommend,as beaconroot is not finished and selfdestruct requires a lot of local knowledge.

@rakita makes sense—thanks for the update!

I think I might leave 4844 up to you—it's true that it's quite sensitive to get right as a bug here affects reth upstream, and I'm not as familiar with the EIP as a whole, nor any upstream assumptions we might have from reth.

For now foundry is on latest main and unblocked the sol team, so it should be good for now for 1153 👍
