ERC20Votes._writeCheckpoint(ERC20Votes.Checkpoint[],function(uint256,uint256) returns(uint256),uint256) (ERC20Votes.sol#236-250) uses a dangerous strict equality:
- pos > 0 && ckpts[pos - 1].fromBlock == block.number (ERC20Votes.sol#245)
Don't use strict equality to determine if an account has enough Ether or tokens.

ERC20Votes._moveVotingPower(address,address,uint256).oldWeight_scope_0 (ERC20Votes.sol#230) is a local variable never initialized
ERC20Votes._moveVotingPower(address,address,uint256).newWeight_scope_1 (ERC20Votes.sol#230) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

ERC20Permit.constructor(string).name (draft-ERC20Permit.sol#35) shadows:
- ERC20.name() (ERC20.sol#61-63) (function)

Rename the local variables that shadow another component.

Variable 'ECDSA.tryRecover(bytes32,bytes).r (ECDSA.sol#59)' in ECDSA.tryRecover(bytes32,bytes) (ECDSA.sol#54-83) potentially used before declaration: r = mload(uint256)(signature + 0x20) (ECDSA.sol#76)

Variable 'ERC20Votes._moveVotingPower(address,address,uint256).oldWeight (ERC20Votes.sol#225)' in ERC20Votes._moveVotingPower(address,address,uint256) (ERC20Votes.sol#218-234) potentially used before declaration: (oldWeight,newWeight) = _writeCheckpoint(_checkpoints[dst],_add,amount) (ERC20Votes.sol#230)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

ERC20Votes.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (ERC20Votes.sol#143-160) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= expiry,ERC20Votes: signature expired) (ERC20Votes.sol#151)
ERC20Permit.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (draft-ERC20Permit.sol#40-59) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,ERC20Permit: expired deadline) (draft-ERC20Permit.sol#49)
Avoid relying on block.timestamp.
