@charles-cooper @ekpyron There’s a topic we’d like some feedback on.
The revamped calls change the stack return values from
0-failure, 1-success - for original CALLs
to:
0-success, 1-revert, 2-failure (and possibly more failure codes c.f. this PR thread
Note that success and failure are flipped. Would this be problematic? In particular (from @shemnon ):
I have concerns about flipping the outputs of calls. e.g. 1 is success vs 0 is success. Specifically for how it will impact the low-level call functions - Units and Globally Available Variables — Solidity 0.8.26 documentation (call, delegatecall, staticcall) as well as inline assembly. Have solidity and vyper chimed in on it on how they would handle it? i.e. would there be compatibility for call and friends and a new variant that will only work when the EOF mode is flipped? and inline assembly would fail if compiled with the wrong mode?
