Pragma version don't use chaort :
Aura.sol,AURaBalRewardPool.sol,AuraClaimZap.sol,AuraLocker.sol,AuraMerkleDrop.sol,AuraMath.sol,AuraMinter.sol,AuraPenaltyForwarder.sol,ClaimFeesHelper.sol,BalLiquidityProvider.sol,

Best practice because in development and testing you can use different versions and cause bugs
No check for address zero and can do some weird thing to the functionality and contract,function you can save gas because your using to storage mappings and you dont have to add it if you have zero address.
