@rory-ocl does this feature seems rational to you? we're currently implementing them by ourselves.

This would mean that pub enum Error that contains these Solidity errors (defined inside sol!) would have to inherit SolError as well, otherwise there may be problems with exporting ABI (see OpenZeppelin/rust-contracts-stylus#439 (comment)).
