Incorrect Exponentiation

What it does​

Warns about ^ being a bit XOR operation instead of an exponentiation.

Why is this bad?​

It can introduce unexpected behaviour in the smart contract.

Example​

    #[ink(message)]
    pub fn exp_data_by_3(&mut self) {
        self.data ^= 3
    }

Use instead:

    #[ink(message)]
    pub fn exp_data_by_3(&mut self) {
        self.data = self.data.pow(3)
    }
