Low level call in Address.sendValue(address,uint256) (#336-342):
- (success) ={value: amount}() (#340)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#415-441):
- (success,returndata) ={value: weiValue}(data) (#424)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
