Issue strange_setter

[VuKhuongDuy]

I have a smart contract like this, I don't understand why it receive error strange_setter
This is my contract

// SPDX-License-Identifier: MIT

pragma solidity 0.7.6;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract Token is ERC20 {
    constructor(
        string memory name,
        string memory symbol,
        uint256 supply
    ) ERC20(name, symbol) {
        _mint(msg.sender, supply);
    }
}

This is error:

Function Token.constructor(string,string,uint256) (contracts/Token.sol#8-14) is a strange setter. Nothing is set in constructor or set in a function without using function parameters

The pess-strange-setter detector examines whether any changes are made to state variables using function parameters. In your case, if nothing is set to state variables in either the constructor function or the _mint function, the detector will indicate that something might be wrong and you'd better double-check it.

However, it is worth improving as it's obviously a FP in your case.
We'll do that, thanks for pointing out.

Merged fixes with #170.
