RUNE Token

RuneToken._writeCheckpoint(address,uint32,uint256,uint256) (#1102-1120) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1112)
Don't use strict equality to determine if an account has enough Ether or tokens.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

Redundant expression "this (#25)" inContext (#15-28)
Remove redundant statements if they congest code but offer no value.

RuneToken.setFeeInfo(address,address,address,uint256,uint256,uint256) (#1137-1149) should emit an event for:
- vaultFee = _vaultFee (#1146)

Low level call in Address.sendValue(address,uint256) (#449-455):
- (success) = recipient.call{value: amount}() (#453)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#528-554):
