CoinAlpha._rTotal (#476) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
CoinAlpha._max_tx_size (#482) is set pre-construction with a non-constant function or state variable:
- _rTotal
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Low level call in Address.sendValue(address,uint256) (#295-301):
- (success) = recipient.call{value: amount}() (#299)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#361-382):
- (success,returndata) = target.call{value: weiValue}(data) (#365)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
