Refactoring - Inline temp

This refactoring is the reverse of the Explaining variable.

You added a new variable to make the code clearer. But after few changes the variable is not really useful.

Consider the following piece of code:

class User {

    var isAdmin: Bool = true

    //...

}

let user = User()

var userIsAdmin = user.isAdmin

if userIsAdmin {

    //do something

}

It is obvious that userIsAdmin is not really needed. We can easily remove it and have the following code:

class User {

    var isAdmin: Bool = true

    //...

}

let user = User()

if user.isAdmin {

    //do something

}
