add support for arg names in return type

[zhiqiangxu]

Component

Cast

Describe the feature you would like

Currently cast call doesn't support arg names in the return type, so this works:

(it's trying to fetch result from the findLatestGames method)

and this doesn't work(the only difference is: the return type also includes arg names):

It would be better and more consistent to support arg names in the return type.

It actually looks like something with the sig you pass, this works OK

cast call 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 "balanceOf(address owner)(uint256 balance)" 0x.. --rpc-url $RPC_URL
8200000000000000 [8.2e15]

Please check your function sig and reopen with details to repro if still an issue. Thank you

@grandizzy Sorry for the late response, it's deployed on sepolia, and can be reproduced with this command:

cast call 0xa1d03c5403aa47d27e8e8c4974b1f675933ebab2 'findLatestGames(uint32 _gameType,uint256 _start,uint256 _n)((uint256 index,bytes32 metadata,uint64 timestamp,bytes32 rootClaim,bytes extraData)[])' 1 0 1 --json -r http://88.99.30.186:8545/

reopenening to investigate per above comment, it happens with array of structs (to be investigated if possible to fix, not sure how we should handle this)

Needs to be fixed in alloy-json-abi or sol-type-parser
