 * {ERC20Votes}: support for voting and vote delegation.
 * {ERC20Wrapper}: wrapper to create an ERC-20 backed by another ERC-20, with deposit and withdraw methods. Useful in conjunction with {ERC20Votes}.

 * {ERC1363}: support for calling the target of a transfer or approval, enabling code execution on the receiver within a single transaction.
