RFIToken.allowance(address,address).owner (#568) shadows:
- Ownable.owner() (#447-449) (function)
RFIToken._approve(address,address,uint256).owner (#653) shadows:
- Ownable.owner() (#447-449) (function)
Rename the local variables that shadow another component.

RFIToken._rTotal (#499) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
RFIToken._previousTaxFee (#518) is set pre-construction with a non-constant function or state variable:
- _taxFee
RFIToken._previousBurnFee (#520) is set pre-construction with a non-constant function or state variable:
- _burnFee
RFIToken._previousFundFee (#522) is set pre-construction with a non-constant function or state variable:
- _fundFee

Low level call in Address.sendValue(address,uint256) (#322-328):
- (success) = recipient.call{value: amount}() (#326)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#388-409):
- (success,returndata) = target.call{value: weiValue}(data) (#392)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
