A "Safe" ERC20 built-in library could be a good example here `safe_erc20.vy`: ```python def transfer(token: ERC20, receiver: address, amount: uint256): # Handle call return data inconsistencies in implementations... def transferFrom(...):...

An importable module can define: - struct - interface - constant - function (that does not access storage e.g. "pure")

For giggles, can you try `METHOD_ID: constant(bytes4) = 0x12345678`?

Just gonna leave this here: https://eips.ethereum.org/EIPS/eip-2678 highlights: - EVM native artifacts - can publish to decentralized (really good for build reproductions) or centralized infrastructure - no need to re-build anything...

@davidhewitt you mean something like: ```rust #[pymodule] mod my_mod { #[pyexception] enum MyException { ... } ... } ```

Oh! I really like that!
