Compare 3 values (check if same)

Does anybody know of a shortcut to compare if 3 numbers are the same? I know this works;

if number1 == number2 && number2 == number3 {

}

But I would like something cleaner, such as;

if number1 == number2 == number3 {

}

It's quite important as I'm comparing a lot of different values, thank you.
