SafeBabyDoge.addLiquidity(uint256,uint256) (#1074-1087) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1079-1086)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

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.

SafeBabyDoge.addLiquidity(uint256,uint256) (#1074-1087) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1079-1086)
Ensure that all the return values of the function calls are used.

Rename the local variables that shadow another component.

SafeBabyDoge.setNumTokensSellToAddToLiquidity(uint256) (#1251-1253) should emit an event for:

SafeMath.trySub(uint256,uint256) (#108-111) is never used and should be removed
Remove unused functions.

Additional information: link

SafeBabyDoge._previousPoolFee (#783) is set pre-construction with a non-constant function or state variable:
- _poolFee
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.functionDelegateCall(address,bytes,string) (#547-553):
- (success,returndata) = target.delegatecall(data) (#551)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Use: Ether suffix, Time suffix, or The scientific notation

SafeBabyDoge._tTotal (#764) should be constant
Add the constant attributes to state variables that never change.

setPoolAddr(address) should be declared external:
- SafeBabyDoge.setPoolAddr(address) (#1255-1259)
Use the external attribute for functions never called from the contract.
