BGF.burnFeeReceiver (#241) is set pre-construction with a non-constant function or state variable:
- DEAD
BGF.totalFeeTransfer (#232) is set pre-construction with a non-constant function or state variable:
- transferRewardFee + transferMarketingFee + transferLiquidityFee + burnFee
BGF.totalFeeSell (#220) is set pre-construction with a non-constant function or state variable:
- sellLiquidityFee + sellRewardFee + sellMarketingFee + burnFee
BGF.totalFeeBuy (#226) is set pre-construction with a non-constant function or state variable:
- buyLiquidityFee + buyRewardFee + buyMarketingFee + burnFee
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.

Pragma version>=0.7.0<0.9.0 (#3) is too complex
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in BGF.swapBack(address,address) (#407-498):
- (tmpSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#491)
- (tmpSuccess2) = address(rewardFeeReceiver).call{gas: 30000,value: amountBNBReward}() (#492)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
